ZW32 series auto circuit recloser, produced by Gopower auto recloser manufacturer, are used in distribution systems. Auto distribution line circuit reclosers are used to make and break normal and fault currents. VCB pole mounted auto reclosers are fully equipped with sensors and a controller to provide protection and control. In case of a line fault, automatic circuit reclosers can break and make currents several times, thus avoiding longer network interruptions due to temporary faults.
As a vacuum circuit breaker automatic recloser manufacturer, we manufacture, design, and test the pole mounted vacuum circuit breaker based on current standards IEC 62271-100. Gopower, which is the standard for China VCB circuit breaker manufacturer to produce qualified vacuum circuit recloser and offer satisfying services for the customers. If you want to buy a automatic recloser circuit breaker, please contact us, because our electrical recloser circuit breaker price is competitive in the recent market.
Outdoor auto recloser circuit breaker is an indoor power distribution 3 phase recloser in 11kv, 24kv, 33kv, normal 24kv vacuum circuit breaker can be used for the protection and control of electrical equipment in industrial and mining enterprises, power plants and substations. The outdoor automatic recloser circuit breaker is especially suitable for places requiring no oil, less maintenance and frequent operation. The vacuum type recloser circuit breaker as pole mounted disconnect switch can be configured in central cabinet, double-layer cabinet and fixed cabinet as control and protection of high-voltage electrical equipment.
As an electric power equipment company, we can offer types of VCB auto recloser circuit breakers, such as 11kv auto reclosers, 33kv automatic circuit recloser, etc.
Pole mounted auto recloser is named because its arc extinguishing medium and insulating medium of contact gap after arc extinguishing is high vacuum. Pole mounted recloser has the advantages of small volume, lightweight, suitable for frequent operation and arc extinguishing without maintenance. Vacuum type circuit breaker is widely used in a distribution network.
High power recloser, referred to as recloser pole, is a high-voltage switchgear with its own control and protection functions. Automatic circuit recloser can automatically detect the current passing through the main circuit of the recloser, automatically disconnect the fault current according to the inverse time limit protection in case of fault, and reclose multiple times according to the predetermined delay and sequence.
Recloser vs circuit breaker are as follows: the pole mounted auto recloser is a kind of high-voltage switchgear with its own control and protection functions; it can automatically detect the current through the main loop of the recloser, protect the fault current automatically according to the reverse time limit in the event of failure, and coincide multiple times according to the predetermined delay and sequence. A automatic recloser circuit breaker is a switching device that can close, carry and open current under normal loop conditions and can close, carry and open current under abnormal loop conditions within a specified period of time.
Vacuum load break automatic recloser switch mainly includes three parts: vacuum arc extinguishing chamber, electromagnetic or spring operating mechanism, support and other components. The working principle of pole mounted recloser is: when the moving and static contacts are opened under the action of the operating mechanism, an arc is generated between the contacts, and the contact surface volatilizes steam at high temperatures. Because the contact is designed in a special shape, a magnetic field is generated when the current passes through. Under the action of this magnetic field, the arc moves rapidly along the tangent direction of the contact surface, and some metal steam condenses on the metal cylinder (shielding cover). The arc extinguishes when it naturally crosses zero, and the dielectric strength between the contacts recovers rapidly. This is the principle of vcb breaker operation.
The arc extinguishing principle of the automatic circuit recloser is: like any kind of high-voltage switch, extinguishing the arc depends on the interrupter chamber. The interrupter is the heart of a high-voltage switch. When the movable and static contacts of the switch are separated, under the action of high electric field, the media particles around the contacts become ionized, thermally free and collisionally free, thus producing an electric arc.
As one of auto recloser manufacturer, we manufacture VCB recloser circuit breaker according to its working principle of vcb. If the moving and static contacts are in an absolute vacuum, when the contacts are opened and closed, no arc is generated because there is no material present, and the circuit is easily broken. If you want to know more details about VCB breaker working principle, please contact us.
Auto recloser circuit breaker has been widely used in China. Especially in the field of medium voltage vacuum circuit breaker, our automatic reclosers have obvious advantages. VCB automatic recloser circuit breaker is now widely used in power systems and has become the key electrical for the effective control of power supply and consumption system. In practical work, only by fully understanding its performance requirements, finding problems in time and taking corresponding measures can we ensure the safe, reliable and economic operation of power supply and consumption system.
ZW32-24/630-20 type automatic circuit reclosers is widely used in urban power grids or rural power grids as a section switch or contact switch, for outdoor substations of the rural power distribution system as an outlet switch, for 10kV system as a split and combined load current, overload current, and short circuit current protection.
