Description
Technical field
The utility model is related to breaker accessory technical field, particularly belongs to a kind of parallel-connection structure for breaker.
Background technology
Breaker be the electric current that refers to close, carry and cut-off under normal loop condition and can close, regulation when
The interior switching device for carrying and cut-offfing the electric current under abnormal loop condition.Breaker is divided into primary cut-out by it using scope
With low-voltage circuit breaker, high-low pressure identification of boundaries is relatively obscured, typically by the referred to as High-Voltage Electrical Appliances of more than 3kV；Breaker can be used to
Distribution electric energy, infrequently starts asynchronous motor, power circuit and motor etc. is carried out and is protected, when their generations are serious
When overload or the failure such as short-circuit and under-voltage can automatic shutdown circuit, its function equivalent to Fuse switch with cross underheat relay
The combination of device etc..And it is latter in disjunction fault current as need not change parts；Electricity generation, conveying, when using, distribution
It is an extremely important link.Distribution system includes transformer and various high and low voltage electrical equipment equipment, and low-voltage circuit breaker is then one
Plant and use the electrical equipment having a large capacity and a wide range.
After repeatedly closing/closing, internal parts occur a certain degree of damage to breaker, when this damage accumulation
After to a certain extent, breaker will break down, to causing the service life of breaker to be limited, in old breaker
During damage, needed circuitry cuts during the breaker for more renewing, and its influence circuit operation.
Utility model content
The purpose of this utility model there is provided a kind of parallel-connection structure for breaker, overcome prior art not
Two breakers are integrated into a new breaker with dual fail-safe by foot by a kind of parallel-connection structure for breaker,
When one breaker is damaged, standby breaker can be timely opened, greatly shorten the down circuitry time, in parallel-connection structure
Fixed conductive plate and active conductive plate on be equipped with bur, during wiring, will directly be enclosed with insulated hull wire insertion wiring
Hole, is extruded by hold-down bolt, and bur punctures insulated hull and is inserted into conductor wire, and easy-to-connect is quick, while overall structure is simple
It is single, low cost of manufacture, it is easy to promote and use, accord with the demands of the market.
