Floor type demarcation switch integrated prepaid metering device is a post. The upper high-voltage metering, switch, and control box are changed to a cabinet-type structure. The integrated prepaid metering device is a combination of column, upper-voltage metering, switch, and control box. It is a product with a cabinet structure, which is composed of an integral cast dry high-voltage metering box and a ZW32F intelligent boundary switch. The box is made of stainless steel or iron plate spray material. This product is easy to install in structure, beautiful in appearance, composed of high pressure metering box and ZW32F intelligent boundary switch, the box body is made of stainless steel or iron plate spray material.

ZWJ-12 type electric load control metering box (hereinafter referred to as metering box) is mainly used for power users and substation areas with rated voltage of 10kV, rated frequency of 50Hz, capacity of 5000kVA and below, and plays the role of load control and high-voltage energy measurement . In cooperation with the load control terminal or other controllers, functions such as load control, high-voltage metering, high-voltage prepayment, overload current protection, and electricity theft prevention can be realized.

JLSZK-12F prepaid high-voltage combined transformer is composed of ZW8-12 outdoor AC high-voltage vacuum circuit breaker and built-in voltage transformer and current transformer, equipped with a control metering box.

This product is suitable for indoor AC 50Hz, rated voltage 3.6kV, 7.2kV, 12kV, 24kV, 40.5kV system. It can be used in conjunction with other switching appliances such as load switches and vacuum contactors. It is also a necessary accessory product for high-voltage switch frame, ring network frame, and high/low voltage prefabricated substations.

This product is used in indoor AC 50Hz, rated voltage 3.6-40.5kV system as overload and short circuit protection of voltage transformer. (Passed the type test of the National High-voltage Electrical Appliance Quality Supervision and Testing Center, and the product complies with GB15166.2 and IEC282-1).

RN indoor high voltage current limiting fuse

Drop-out fuses and pull-load drop-out fuses are outdoor high-voltage protection appliances. It is installed on the high-voltage side of the distribution transformer or on the branch and trunk lines of the distribution line, and is used for short-circuit and overload protection of the transformer and the line, as well as the split and combined load current. The drop fuse is composed of two parts: an insulating bracket and a fuse tube. The static contact is installed at both ends of the insulating bracket, and the moving contact is installed at both ends of the fuse tube. The fuse tube consists of an inner arc suppression tube and an outer layer. phenolic paper tube or epoxy glass cloth tube. The load drop type fuse enhances the elastic auxiliary contact and arc extinguishing cover to divide and combine the load current.
