大连Outdoor high-voltage vacuum switch type prepaid metering device
Product Description
Product Overview
The JLSZK-10W prepaid combination current transformer is suitable for 50HZ rated, 10KV rated voltage three-phase power lines, realizing prepaid electricity metering, remote control, meter reading, and anti-theft functions. This product has a compact structure, powerful functions, small size and light weight, safety and reliability, and easy installation.
This product consists of a high-voltage main box and a control box. The high-voltage main box consists of a high-voltage current transformer chamber and a high-voltage vacuum contactor chamber. The high-voltage primary lead is led out through a high-voltage silicone rubber bushing. The secondary lines and control lines are led out from the box and connected to the control box through K-type cables or plastic-sealed metal flexible tubes. The control box consists of an electricity meter, a control terminal, and a control circuit. The high-voltage current transformer consists of two or three components (two voltage transformers connected in V/V, two current transformers). The current transformer can be made into a double current ratio (at the secondary winding tap) according to user needs.
The control box door panel is equipped with on/off indicator lights. It can display the high-voltage operating status and the remaining electricity fee.
