SF6 circuit breaker inspection items in operation, do you know what items need to be checked during the operation of SF6 circuit breakers? Today we will explore the specific inspection items.
1. Mechanical operation status check
1.1 Confirm whether the mechanical cabinet door is closed tightly to prevent external dust and moisture, which will affect the service life of the equipment.
1.2 Confirm whether the mechanical operation of the circuit breaker is smooth, if you find the phenomenon of jamming or jamming, you need to check and repair in time.
1.3 Check the leakage of mechanical parts, especially SF6 gas, need to pay attention to whether there is leakage.
2. air pressure check
2.1 Check the air pressure meter to confirm the air pressure when the circuit breaker is working, and the reading of the air pressure meter should be in accordance with the specified range.
2.2 Check whether there is any leakage of SF6 gas, and pay attention to whether there is any abnormal odor.
3. Electricity consumption check
3.1 Check whether the power consumption of the equipment exceeds the standard, and if abnormal exceeding is found, the reason needs to be investigated in time.
3.2 According to the equipment specifications and power consumption to confirm whether the main parameters of the circuit breaker is stable, whether the working effect is normal.
4.electrical performance check
4.1 Confirm the fixing of the circuit breaker terminal board to prevent the terminal board from loosening or falling out of the wrong phenomenon.
4.2 Check whether the electrical connection lines and metal parts of the circuit breaker are corroded and loose, etc., so as to avoid the failure of electrical equipment caused by short-circuit and poor contact in the course of use.
4.3 Check whether the mechanical and electrical parts of the circuit breaker have accumulated dirt and dust, etc., if necessary, clean up and maintain in time.
in conclusion:
The above is the check items in the operation of SF6 circuit breaker, through regular inspection and maintenance, can guarantee the normal use of equipment and working effect.
