Description
Technical field
This utility model is related to chopper used in a kind of circuit of open air.
Background technology
Chopper be refer to the electric current that closes, carry and cut-off under normal loop condition and can close, regulation when
The interior switching device carrying and cut-off the electric current under abnormal loop condition.Chopper is divided into primary cut-out by its range
With low-voltage circuit breaker, high-low pressure identification of boundaries is fuzzyyer, typically by the referred to as High-Voltage Electrical Appliances of more than 3kv.Chopper can be used to
Distribution electric energy, infrequently starts asynchronous motor, carries out protection to power circuit and motor etc., when their generations are serious
When overload or the fault such as short-circuit and under-voltage can automatic shutdown circuit, its function is equivalent to Fuse switch and crosses underheat relay
The combination of device etc..And typically do not need to change parts after disjunction fault current.At present, obtain a wide range of applications.
Electricity generation, conveying, use in, distribution is an extremely important link.Distribution system includes transformator and various high-low pressure
Electric equipment, low-voltage circuit breaker is then a kind of using the electrical equipment having a large capacity and a wide range.
The main contacts of low-voltage circuit breaker is by manual operation or electric switch-on.After main contacts closure, free tripping mechanism
Main contacts is locked on closing position.The thermal element of the coil of overcurrent trip and thermal trip is connected with main circuit, owes electricity
The coil of pressure electrical apparatus release and power sources in parallel.When circuit is short-circuited or during heavy overload, the armature adhesive of overcurrent trip, make
Free tripping mechanism action, main contacts disconnects main circuit.When circuit overloads, the thermal element heating of thermal trip makes bimetal leaf
Upper bending, promotes free tripping mechanism action.When circuit under-voltage, the armature release of under-voltage release.
Existing chopper insulation effect is general at present, safety general it has not been convenient to remote control.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of insulation effect good, safe and reliable, Stability Analysis of Structures
Property high, chopper used in the outdoor circuit of achievable remote control.
For solving the above problems, this utility model adopts the following technical scheme that chopper used in a kind of circuit of open air,
Including insulation crust, conductive pillar, iron core and coil, described conductive pillar and iron core are located in insulation crust, described conductive
Post is fixedly connected with insulation crust respectively with iron core, and described coil is arranged on outside iron core, and described conductive pillar is provided with rank
Ferrum, described armature is hinged with conductive pillar, and described armature is provided with insulation board, is provided with short-circuited conducting sleeve, institute below described armature
State insulation board one end and spring is installed, described spring bottom is connected with regulating bolt, described insulation board is provided with roller and draws
Bar, described pull bar is in bending setting, and described pull bar one end is provided with rotating shaft.
Preferably, described insulation board is fixedly connected with armature, holding structure is reliable and stable.
Preferably, described regulating bolt is threadeded with insulation crust, the position of easily dimmable spring.
Preferably, described roller is located at pull bar end, pull bar is facilitated to adjust the position of roller.
Preferably, being provided with support bar below described rotating shaft, holding structure is reliable and stable.
The beneficial effects of the utility model are: the insulation crust of setting and insulation board can keep insulation effect good, use
Safe and reliable；The roller of setting and the convenient position adjusting armature of pull bar, holding structure stability is high；The coil of setting is in energising
The position that armature can be adjusted afterwards at a distance keeps manipulation convenient.
