What are the precautions when switching the brake?

Electrical equipment is divided into three states: operation, standby and maintenance. The process of changing one state of equipment to another state is called switching, and this operation is called switching operation.

Safety technical measures for switching operation

1. Any switching operation must be carried out under the overall command of the switching commander and monitored on site. Switching operation must use switching operation ticket.

2. Before braking, the brake head should check the running equipment lines and switches. Check whether it is in good condition before switching.

3, in the process of brake, the operator should pay attention to the order, to prevent the load brake.

4. When switching, close the contact switch and power switch of the motor room first, and then close the isolating knife and oil switch of the power switch of the motor room. At this point, check whether the running equipment has a power indicator; If there is no instruction, stop the operation immediately and find out the reason.

5. When the running circuit has been put into operation, power off the oil switch and isolating knife of the other circuit of the machine room first, and then power off the power switch of the machine room, and hang warning signs on the two switches.

6, after the brake, by the personnel on duty (operators) to recover and keep the working ticket.

Analysis of dangerous points in switching operation

1. Do not carefully check the equipment name, number and location before operation.

2, single operation or no ticket operation.

3. Do not carefully check the switch position before opening and closing the circuit breaker.

4. Do not check the electricity before installing the grounding wire (grounding circuit breaker).

5, before sending, don't carefully check whether all safety measures within the scope of sending are removed.

6. Precautionary measures for dangerous points in switching operation

(1) The name, number and location of the equipment must be carefully checked before switching operation.

(2) Any operation must be carried out by two people, and it is forbidden to operate by one person.

(3) Before opening and closing the circuit breaker, ensure that the switch is in the off position.

(4) Check the electricity before installing the grounding wire (grounding knife).

(5) Before sending, it must be checked that all grounding wires have been removed and all grounding knife switches have been opened.
