The Split Meter Ready Board wholesaler said that the ambient temperature has an impact on low-voltage electrical apparatus, which is also prone to failure. Therefore, during the use, the upper limit of the ambient air temperature shall not exceed 40 ℃, the average value of the ambient air temperature within 24h shall not exceed 35 ℃, and the lower limit of the ambient air temperature shall not be lower than -5 ℃ or -25 ℃.

1. dredge the drainage ditch around the substation, conduct moisture-proof treatment for the cable trench, and add a high-power industrial dehumidification air conditioner on the first floor of the substation. The indoor temperature of the distribution room shall be controlled at 23 ± 2 ℃ in summer and 20 ± 2 ℃ in winter. The relative humidity of the air in the distribution room shall be strictly controlled at 40% ~ 50%. The on-line temperature and humidity monitoring device shall be installed in the power distribution room. Once abnormal temperature and humidity are found, it shall be adjusted in time to ensure the safe and stable operation of the switchgear and relay protection device.

2. add silicon rubber insulating plate between pole posts of circuit breaker handle and between pole posts and rear side plate. Increase the number of patrol inspections in summer.

3. to ensure that no pollution flashover accident occurs, the bushings of current transformers, voltage transformers, high-voltage circuit breakers, lightning arresters, live display devices, knife switches and other equipment, as well as supporting insulators, shall be cleaned and fastened regularly. Anti pollution paint shall be applied outside the insulator in the heavily polluted area.

4. the increased climbing distance skirt of silicone rubber is about 100 mm larger than the external insulation umbrella of electrical equipment. Silicone rubber is added to the surface of equipment porcelain parts to prevent equipment from pollution flashover. I hope I can help you through the relevant introduction of the above Split Meter Ready Board wholesale manufacturers. If you have other questions, you can consult our company at any time.
