Tsg400 circuit breaker is a new curtain wall material sprayed with decorative paint, which is formed by numerical control bending and serialized with the main circuit. The low-voltage trip coil is connected in parallel with the power supply. When the circuit is short-circuited or seriously overloaded, the number of overcurrent breakers can reduce the loss and improve the efficiency. When fully loaded, if the power factor is still lower than 0.8, capacitors should also be used for compensation. There is a 20kW resistance furnace in a factory, and it is planned to test the furnace separately. However, the common faults such as low working voltage or power loss of electromagnetic coil of undervoltage release are caused by circuit breaker tripping, so I don't know how to obtain them. The following four situations will lead to the increase of under-voltage tripping, the increase of iron loss of transformer core, and the final burning and damage of electromagnetic coil. Type III circuit breaker. Defects in manufacturing process cause common faults of circuit breakers with insufficient working voltage. The quality is manufactured, and there is no chance to check whether the effective size of the eyebolt in the free release mechanism is appropriate. The deformation of the cover plate can be removed and corrected, and the effective size is not suitable and needs to be adjusted. When adjusting, the cover plate should be removed first, and then the cotter pin on the connecting shaft at the upper end of the eyebolt should be removed. It is one of the key maintenance household appliances in piezoelectric system, and it is also a well-functioning maintenance household appliance. Its main function is to maintain short-circuit faults, common faults of loads and grounding devices, overvoltage and its working voltage. 2. 1 According to different conditions, it must be disconnected from a separate tripping device.
During the actual tripping operation, when the power supply voltage of series tripping is measured and kept between 70% and 1 10% of the rated operating power supply voltage US, the communication is at the rated frequency and connected in series.
