Zw32 AC high voltage automatic recloser (hereinafter referred to as recloser) is composed of zw32-24c AC high voltage circuit breaker (hereinafter referred to as circuit breaker) and st300c reclosing controller (hereinafter referred to as reclosing controller). It can automatically conduct breaking and reclosing operation in AC line according to predetermined breaking and reclosing sequence, and then automatically reset or lock, and has the function of control and protection Pressure switch equipment. The product conforms to iec62271-111 standard.
1. Zw32-24c AC high voltage circuit breaker is an Outdoor Switchgear installed on power station or pole. It is mainly used in the transmission and distribution system with rated voltage of 24kv.22kv.20kv.three-phase AC 50 / 60Hz, switching rated current and short-circuit current. It is mainly used in urban and rural distribution network and 20-24kv substation. The secondary control line of the equipment can be connected with the reclosing control button after the air joint of the secondary control line is released, so that the product can be easily upgraded to automatic recloser.
2. Zw32-24cz AC high-voltage recloser not only has the functions of opening and closing rated current and short-circuit current, but also has 0-4 reclosing, constant / inverse time limit current protection, zero sequence current protection, voltage loss protection, etc. At the same time, it has the function of fault recording. It can also be used for switching in ring network. The product is equipped with RS485 / 232 communication interface and iec870-101 communication protocol. It can be connected with monitoring system to realize four remote and remote communication. The reliability of distribution system is greatly improved by timing and comprehensive self-test system.
