ZW(AB-3S) type of outdoor high voltage permanent magnetic vacuum automatic recloser

SUMMARY
ZW□(AB-3S) type of outdoor high voltage permanent magnetic vacuum automatic recloser (hereinafter referred to as the "coincidence") is rated voltage 12kV, outdoor power distribution switch three-phase AC 50Hz, recloser is my company to meet the demand of smart grid and the development of a new generation of outdoor column switch for switching loads of various kinds and frequent operationoccasions, and has repeatedly ability to interrupt short circuit current.It can be used as substation main transformer 24kV side outlet and switch on the power distribution net, is the realization of distribution automation and miniaturization of substation equipment first.The coincidence device is composed of a SYW1-12 permanent magnet vacuum circuit breaker and a CPT-31G type superposition controller, which has the functions of measurement, protection, control, communication and detection.Coincidence device in accordance with GB1984-2003, JB/T7570-1994 and IEC60056 and other technical standards.
MODEL & IMPLICATIONS

Characteristic

1 vacuum arc extinguishing, reliable disconnection, contact wear is small, maintenance free;
2 independent three-phase permanent magnetic actuator, simple and fast, stable and reliable, without nurturing; three institutions units connected with a three-phase vacuum interrupter action, ensure the mechanism and characteristic of each phase of arc chamber,Reliable guarantee for the operation sequence of the coincidence device: the successful completion of the sub -t1 (0.3s) - -t2 (3S) - -t3 (3S) - sub - locking;
3 external insulation materials imported outdoor epoxy resin, pressure and weathering, no oil, no SF6 gas, environmental protection;
4 with protection, measurement, control, communication, detection and other functions, the real-time operation state of the device is reliable;
5 built in moisture protection, low temperature protection control, the control system can work reliably at the limit of moisture and low temperature conditions;
6 with the distribution network dedicated power module, the battery can be online monitoring and activation management, to extend the battery life, improve the reliability of the power supply system;
7 with remote communication interface, the distribution network automation can be realized through Ethernet optical fiber network or GPRS channel;
8 remote / local control function, while the local radio remote control, under the pole operation;
9 friendly man-machine interface, full Chinese display, convenient parameter setting;
10 high quality stainless steel manufacturing, no corrosion, and truly realize the name of maintenance.
