1250A Automatic Electric Vacuum Circuit Breaker Maintenance Free With Controller For Outdoor With Isolation Switch

1250A  Automatic Electric Vacuum Circuit Breaker Maintenance Free With Controller For Outdoor With Isolation Switch

Product Description:

This automatic vacuum circuit breaker is the rated voltage of the three-phase ac 50HZ outdoor distribution equipment, its rated current is 630A~1250A,short-current is 20kA.It mainly used forloading current,overcorrect and short current which use cut-off and close-open electricity system.It is suitable for industrial and mining establish company while its aim is to protect and control the system and easy to suit the rural and some frequent operation place.

Controller Introduction:

1.With 485 / 232 communication interface, or through optical fiber, wireless remote monitoring; Acceleration function after reclosing;when the switch is heavy,automatic acceleration tripping in case of permanent fault;

2.Remote / manual closing to accelerate tripping, and closing reclosing: The user sends power after repairing the line, if he forgets to remove the grounding switch,should accelerate tripping.

3.Three reclosing delay time can be adjusted;

4.The jump closing circuit adopts anti-misoperation design and has anti-jump function;

5.Zero-sequence current can distinguish between in-zone and out-of-zone faults;

6.The remote control switch is designed to prevent misoperation.

Technical Feature:

1 three-phase pillar fully closed structure with high sealing performance
A.Stable and reliable breaking performance, no combustion and explosion danger; no maintenance, small volume, light weight, long service life.

B.Strong moisture and condensation resistance, especially suitable for use in cold or humid areas.

C.Imported materials have good insulation properties, high temperature resistance, UV resistance, aging resistance.

2 High efficiency and reliable miniaturized skip operating mechanism

A.The power of the energy storage motor is low, the energy consumption of the gate is low, the mechanism transmission adopts the direct action transmission mode, the number of parts is small, and the reliability is high.

B.The operating mechanism is placed in the sealing box to effectively prevent corrosion and improve the reliability of the mechanism.

3 Convenient and flexible manipulation and free combination performance

A.Manual switching /electric division and closing/remote control operation can be used.

B.With the intelligent controller to achieve distribution automation, or with the coincidence controller to form an automatic reclosing device, segmented device.

C.Two-phase or three-phase current transformers can be installed for over-current or short-circuit protection.

D.It can provide current acquisition signal for intelligent controller and install current transformer for metering according to user's request.
E.It can be equipped with three-phase linkage isolating switch, with error-proof interlocking device, and can be connected with lightning arrester pillar insulators for convenient maintenance.

Advantage:

1.Small size

2.Light weight

3.Maintenance free

4.Anti condensation

5.Adapt to adverse weather conditions and dirty environment

Technical Paremeter:

It will double the effect using when the circuit breakers used with isolation disconnector.
