ZW32-12KQ Type Primary And Secondary Full Fusion Column Vacuum Circuit Breaker

ZW32-12/KQ type primary and secondary full fusion column vacuum circuit breaker (hereinafter referred to as circuit breaker) is the latest generation of products developed by our company according to the requirements of the national grid primary and secondary fusion complete set of column switches. The circuit breaker meets the requirements of the national grid primary and secondary fusion set of column switches, the secondary FTU and voltage and current sensor, power module, electronic sensor and primary vacuum interrupter and operating mechanism and other components, all integrated in the circuit breaker, with simple structure, reasonable layout, complete functions, excellent performance, high reliability advantages. All the indexes of the circuit breaker meet the requirements of the national grid’s primary and secondary fusion complete set of column switches. The circuit breaker adopts unified parameter set phase sequence and zero sequence voltage. Phase sequence, zero sequence current and power taking integrated sensor pouring integrated pole, with a wide measuring range, high measurement accuracy, high reliability, measurement, power supply, protection three in one characteristics,FTU adopts the whole life design scheme, the real integration between the primary and secondary integration, due to the reduction of the original primary and secondary feeder connection, reliability is improved. This product combines modern Internet of Things and big data, with “four remote” function, self-test function and remote monitoring and maintenance function, can complete fault detection and reporting in real time, can save a lot of manpower and material resources and time cost for operation and maintenance units, and can effectively reduce the power failure time for users in the case of failure.

This product uses the most advanced circular ceramic capacitor for power collection and sampling, which can maintain stable performance in a variety of harsh environments.
This product adopts innovative design, has independent intellectual property rights, and has obtained a number of national technical patents.
This product has 12 power taking and sampling capacitors (expandable up to 15 capacitors),6 current sampling; The phase voltage and zero sequence voltage of the power supply side and the load side can be sampled and taken, and the phase current and zero sequence current of the load side can be sampled.
Using a new bistable, double coil repulsion + magnetic drive operating mechanism, its structure is novel and simple, small size, fast execution rate, stable action, can achieve synchronous breaking function, reduce the splitting and closing pull arc and current impact, high reliability.
Built-in FTU adopts the whole life design scheme, increase the waterproof, shock-proof and anti-electromagnetic interference design, no output cable, will be integrated once and twice, high reliability, more convenient installation.
Comes with APP handheld operating tablet, automatic connection, password input control.
In order to solve the problem of data transmission in plateau and remote areas, this product has medium voltage online carrier technology, which can realize seamless control and monitoring of the whole region and the whole climate.
FTU, combined with advanced fast fault judgment algorithm, can reliably remove faults from the power supply side in the shortest time, reduce the impact of voltage dips, prevent “fault crossing”, and ensure the operation of other users’ equipment and the normal operation of the power grid.
With built-in temperature compensation constant temperature system, when the ambient temperature is below 0 degrees, it automatically heats the battery to ensure the life and temperature quality of the battery.
The fault detection response time of the circuit breaker controller (from the time when the fault occurs to the time when the controller determines the fault and outputs the breaking instruction) is 2.64ms
Circuit breaker fault removal time (from fault occurrence to fault removal and isolation) 11.68ms
