Applicable environment devices are suitable for power plants, petroleum, chemical industry, metallurgy, etc. In large power plants, petrochemical systems and other places with high degree of automation and need computer interface, it is used as a low-voltage complete distribution device for power distribution, centralized control of motors and reactive power compensation in the power generation and power supply system with three-phase AC frequency of 50(60)Hz, rated working voltages of 380V(400)V and (600)V and rated current of 4000A or less. See attached figure 1 for the basic organizational form of the device. The standard requires the design of the device to meet the following standards: IEC439- 1 Low-voltage switchgear and control equipment GB725 1 Low-voltage switchgear ZBK3600 1 Low-voltage drawout switchgear. The ambient air temperature shall not be higher than+40 C and not lower than-5 C. The average temperature within 24 hours shall not be higher than+35 C. If it exceeds, you need to reduce the capacity according to the actual situation. 2 For indoor use, the altitude of the place of use shall not exceed 2000m m. 3 The relative humidity of the ambient air shall not exceed 50% at the highest temperature+40 C, and relatively high relative humidity is allowed at lower temperatures: for example, 90% at+20 C, so the influence of occasional dew condensation due to temperature change shall be considered. 4 During installation, the inclination between the equipment and the vertical plane shall not exceed 5, and the whole cabinet shall be relatively flat (in line with GBJ232-82 standard). The equipment should be installed in a place where there is no violent vibration and impact, and it will not cause excessive corrosion to electrical components. When users have special requirements, they can negotiate with our company.

The functional rooms of the device are strictly separated, and the compartments are mainly divided into functional unit rooms, bus room and cable room, and the functions of each unit are relatively independent. 3. Cabinet size series (unit: ㎜): height 2200, width 400* 600* 800* 1000, depth 800 *1000 * 800 *1000 * 600. It is divided into five size series: 1/2 units, 1 unit, 1.5 units, 2 units and 3 units. The rated current of the unit circuit is 400A or less. B the drawer only changes in height dimension, and its width and depth dimension remain unchanged. Drawers with the same functional units have good interchangeability. C each GCS cabinet can be equipped with at most 1 1 drawers with one unit or 22 drawers with 1/2 units. Among them, multi-unit drawers adopt multifunctional backboards (see attached figure 18). D different plug-in programs of the same specification are adopted for the incoming and outgoing lines of drawers according to the current. The connection between drawer and cable of e. 1/2 unit adopts ZJ-2 adapter with backboard structure. F according to the current grade, ZJ- 1 adapter with the same size bar or tube structure should be used for the connection between the unit drawer and the cable room. Figure 6 shows the outline of the adapter. G. The drawer panel has obvious marks such as opening, closing, testing and drawing. The drawer unit is equipped with a mechanical interlock device. Feeder cabinets and motor control cabinets are equipped with special cable rooms, and the connection between functional unit rooms and cables in cable rooms is realized through adapters or adapter copper bars, which not only improves the reliability of cables, but also greatly facilitates the installation and maintenance of cables by users. The cable room has two width sizes (240㎜ and 440㎜) to choose from, which depends on the number and cross section of cables and the convenience and requirements of users for installation and maintenance. The number of auxiliary contacts of functional units of the device is 32 pairs with one unit or more and 20 pairs with 1/2 units, which can meet the needs of automatic users and computer interfaces. Considering the general safety of dry-type transformer and the economy of oil-immersed transformer, the device can be conveniently combined with dry-type transformer or connected with low-voltage bus of oil-immersed transformer. Take drawers as the main body, and there are two types: drawer type and fixed type, which can be mixed and selected at will. The device adopts three-phase five-wire system and three-phase four-wire system design, and the design department and users can easily choose PE+N or PEN mode. 10 cabinet protection level is IP30 and IP40, which can be selected according to user's requirements. The device features 1, which improves the heat capacity of the adapter and greatly reduces the extra temperature rise caused by the temperature rise of the adapter to the plug-in, cable head and partition. The separation between functional units and compartments is clear and reliable, and the failure of one unit will not affect the work of other units, thus limiting the failure to a minimum. The horizontal arrangement of three buses makes the device have good dynamic and thermal stability and can withstand the impact of 80/ 176kA short-circuit current. There are as many as 22 circuits in a single MCC cabinet, which fully considers the needs of industries such as large single-machine capacity power generation and petrochemical system for automatic electric doors (machines). The connection between the equipment and the external cable is completed in the compartment with cable, and the cable can go in and out up and down. The zero sequence current transformer is placed in the cable room for easy installation and maintenance. In the same distribution system, the short-circuit current can be limited by matching current-limiting reactors, so that the bus voltage can be stabilized at a certain value, and the requirements for short-circuit strength of components can be partially reduced. 7 The drawer unit has a sufficient number of secondary plug-ins (32 pairs for 1 and above units and 20 pairs for 1/2 units). It can meet the requirements of computer interface and automatic control loop for the number of contacts. After the installed and used products arrive at the receiving place, first check whether the packaging is in good condition. If any problem is found, it shall promptly notify the relevant departments of the contract to make business records, analyze the reasons, and do a good job in visa and after-care treatment. For products that are not installed immediately, they should be placed in a proper place and properly kept according to the requirements of normal use conditions and temporary storage regulations for electrical equipment. 1 The product shall be installed according to the installation diagram (see Figure 1-3, Table 7-9). When the bolt fixing method is adopted, the foundation channel steel and bolts shall be provided by the user. When connecting the main bus, if the surface is uneven due to transportation, storage and other reasons, it should be leveled first, and then connected and fastened. 2 When the equipment is installed separately or in columns, its verticality, unevenness of cabinet surface and deviation of cabinet gap shall meet the following requirements.

The device is a low-voltage distribution cabinet, which is not installed against the wall, and is operated on the front and maintained on both sides. Only qualified professionals can enter or open maintenance channels and doors for operation, inspection and maintenance. B air switch and molded case circuit breaker, after switching on and off for many times, especially after short-circuit switching on and off, will cause local contact burns, produce carbonaceous substances and increase contact resistance. Therefore, they should be maintained and overhauled according to the operating instructions of circuit breakers. C after installation and maintenance, the isolation between isolators and between functional units must be strictly checked to ensure the good functional isolation of the device and prevent the fault from expanding.
