10kV过电压保护器的试验方法与交接相同，做绝缘电阻和工频放电电压，大修后26-31kV，运行中23-33kV。
The test method of 10kV over-voltage protector is the same as that of handover. It is used as insulation resistance and power frequency discharge voltage. After overhaul, it is 26-31kV and 23-33kV in operation.
所有的电器在使用时最忌电网电压过高过低，不论工业设备还是家用电器都有一个额定电压，电压范围通常规定为170V-240V（可以在电器设备的铭牌或说明书上看到）。如果超出这个电压就超出了电器的绝缘强度和耐压值，电器会因此发热、击穿而烧坏甚至起火。

All electrical appliances should avoid too high or too low grid voltage when using. Both industrial equipment geshanb.89ix.comtaiyangn.89ix.comgelidun.89ix.comgangguanp.89ix.comtongshizi.71ix.comzhu

zaojm.37ix.com.cnand household appliances have a rated voltage. The voltage range is usually set at 170V-240V (which can be seen on the nameplate or instructions of electrical equipment). If this voltage is exceeded, it will exceed the insulation strength and withstand voltage value of the electrical appliances, and the electrical appliances will be heated, broken down and burned or even ignited.
