10 KV floor type prepaid breaker integration of metering device is shaanxi tai electric equipment co., LTD., is a product of independent research and development production will post high pressure measuring, switch, control box to the structure of cabinet put oneself in another's product, by integrally casting dry type high voltage metering box or oil-immersed type metering box and ZW32 dividing line switch, intelligent box body is made of stainless steel or iron plate welded material production. This product is easy to install in structure and beautiful in appearance. The high-pressure part is completely isolated from the low-voltage meter room. In addition, the high-pressure room cannot be opened for operation when the equipment is electrified. The product occupies a small area and is a perfect combination of living area, industrial and mining enterprises and box-type transformer. Personnel can directly open the door to view the bottom of the table and operate the switch in place. The transformer is vacuum poured by fully enclosed epoxy resin, so the aging problem is eliminated. The dividing switch adopts vacuum switch with zero sequence and protection current transformer, and realizes zero sequence, over-current and quick-break protection with intelligent controller, which can automatically remove single-phase ground fault and automatically isolate phase short-circuit fault. Ensure the safety of non-fault users. This product has FTU function to realize remote switching and closing; It also has GPRS remote control function.


JLSZK-10KV floor-type pre-paid high voltage metering integration device

ZW32-12 user interface vacuum circuit breaker body adopts three-phase pillar structure, with stable and reliable breaking performance, no combustion and explosion risk, safety, maintenance free, small size, light weight and long service life, etc. It's a maintenance-free product. The main body of the circuit breaker is installed in a pedestal. The boundary controller is installed below the circuit breaker and is connected to the circuit breaker by an outdoor cable. The power transformer (voltage PT) may be placed side by side with the circuit breaker or above it.

B. Flexible and convenient operation electric automatic energy storage, remote control switching on and off. At the same time, it has the functions of manual energy storage and manual separation and closing, which can be directly connected to the rated voltage output of the voltage transformer from the overhead line, transferred through the terminal box on the side of the circuit breaker, and introduced to the controller with the connection cable, which can be operated by the controller remotely.

The operating mechanism adopts miniaturized spring operating mechanism with low energy consumption for opening and closing; Direct transmission mode is adopted for the mechanism transmission, with few opening and closing parts and high reliability. The operation mechanism is placed in the sealed circuit breaker mechanism box, which solves the problem of mechanism corrosion and improves the reliability of the mechanism.

C. Variable ratio arbitrarily adjustable, PT secondary output transit

Switch wire side external zero sequence current mutual inductance and two phase or three phase current transformer, terminal box are set in cover outside side, CT changes than wire leads, PT secondary voltage input terminal, in the terminal box, can do any adjustment of CT variable ratio and PT secondary internal transfer, the power cord by the circuit breaker controller, introduced by outdoor cable, reduce the secondary power line is too long, and the controller are subject to a power supply interface for the inconvenience.
