Rapid arc suppression expert system product name YZ-XH1 series distributionnetwork

Product description

A product is introduced

The arc suppression system is composed of DKSC dry type transformer, XHDC-Kdouble split large leak anti dry controllable arc suppression coil and control systemdeveloped in cooperation with Shanghai Jiao Tong University and small current line selection device. The system can real-time tracking of the distribution network, the compensation effect is excellent for instantaneous single-phase grounding fault andto ensure that it can quickly eliminate fault; the fast non instantaneous single-phasegrounding fault (less than 10S) line selection tripping. It can also be in accordance with the traditional arc suppression coil grounding mode for 2 hours of operation.This technology is the leading domestic, it eliminates the previous variousautomatic tracking various local faults arc suppression device, have their advantages, obtain more ideal effect. This system can be applied to any structurein any capacity, (overhead lines, cable or they are mixed in any proportion) in distribution network.

The XHDC-K series of double split large leak anti dry controllable arc suppression coil is my company self-developed patent product, the "day" type iron core, a high-voltage winding and control winding distribution in different columns, is loosely coupled, leakage resistant, up to 100%, the control winding is composed of two groups of thyristor short circuit, thus by adjusting the controllable silicon conduction angle, can provide compensation inductor current zero to the rated current range,and can realize continuous stepless regulation.

Due to the adoption of "day" type of core structure, greatly reduces the cost of the material, can be reduced about 25% than previous similar properties of arc suppression coil. The transformer core structure, no air gap, which has the advantages of simple process.

The arc suppression coil has two advantages: first, because of the short circuit impedance instead of magnetizing impedance as the working resistance, the volt ampere characteristics can maintain excellent in 0-100% rated voltage range of linearity; second, due to the use of silicon controlled rectifier, thus the fast response speed.
