ZCW10-40.5
L-type open combination electrical appliances
Product Details
Overview
ZCW10-40.5L open type combined electrical appliance is a complete set of combined electrical appliances that uses air as the outer insulation and SF6 gas as the arc extinguishing medium. It is used for the control and protection of the three-phase AC 72.5 KV transmission and distribution system, and can also be used for connecting circuit breakers and opening and closing capacitor banks. It is suitable for urban substations, enterprise substations, and mountain substations with limited land.
Structural features
The circuit breaker is an outdoor small floor-standing tank structure, equipped with a CT35 spring operating mechanism; the mechanism is installed in conjunction with the body, which is simple to install, easy to debug, reliable in action, and suitable for frequent operation; the mechanism life is more than 10,000 times;
It adopts a compressed air arc extinguishing structure, with a particularly strong breaking capacity, and a cumulative breaking of 40kA has reached 12 times, setting a domestic first;
Reliable sealing performance • Imported sealing pads are used, and the dynamic seal adopts a "V" type sealing ring with a spring pressure compensation structure. The transformer secondary terminal board is matched by a joint venture to ensure that the annual leakage rate is less than 0.5%;
The built-in current transformer is made of microcrystalline alloy with high magnetic conductivity, and the accuracy level can reach 0.2 or 0.2s. According to user needs, 12 transformers can be included. Suitable for 50 kilometers of unloaded long lines without reignition.
