Abstract
The utility model discloses a high-performance tripping and closing coil. The high-performance tripping and closing coil comprises a coil winding wire, a framework and a covering layer, wherein the coil winding winds around the cavity on the outer side of the framework, the covering layer is arranged on the outer side of the winding and the framework and the winding winds is made of autohension enameled wire. The high-performance tripping and closing coil utilizes the autohension enameled wire to replace the polyester enameled wire used by conventional tripping and closing coil, so that the enameled wire temperature resistance is enhanced from 130 DEG C to 180 DEG C. The enameled wire of the high-performance tripping and closing coil can be fused and further play a role in insulating at the high temperature of 170 DEG C to 180 DEG C, thereby the service life is prolonged and the reliability of the coil is greatly improved. The enameled wire of the high-performance tripping and closing coil is free of being soaked with electrical insulating paint, so that the coil molding process is shorten, the production efficiency is improved, the pollution of insulating paint to the environment and the high energy consumption of insulating paint drying are avoided and the coil is beneficial to energy conservation and environment friendly.
Description
Technical field
The utility model relates to a kind of divide-shut brake coil, relates in particular to the high high-performance divide-shut brake coil of a kind of insulation property.
Background technology
The divide-shut brake coil is multiplex in electric power system, and divide-shut brake coil burnout accident often occurs in the power system operation.When electric equipment has an accident, if because the circuit breaker misaction appears in the brake division loop of circuit breaker broken string, will make fault spread, cause the separating brake of bypassing the immediate leadership to cause large-area power-cuts, even cause the serious consequences such as power equipment burns, fire.
The coil windings of divide-shut brake coil in the market all adopts polyester enamelled wire to be wound on the skeleton, again coil windings and skeleton is sealed moulding by encapsulated layer integral body.Although the divide-shut brake coil operation time is short, electric current is very large, and heating temp is high.In case prolong because other fault causes conduction time, coil generates heat rapidly, temperature rise speed is very fast, because the temperature resistant grade of existing polyester enamelled wire is 130 ℃, in case the coil heating temperature surpasses 130 ℃, will directly cause insulating barrier destruction and cause failure of insulation, and then burn the divide-shut brake coil.
Summary of the invention
The purpose of this utility model provides a kind of insulation property high high-performance divide-shut brake coil with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Divide-shut brake coil described in the utility model comprises coil windings, skeleton and encapsulated layer, and described coil windings is wound in the cavity in the described skeleton outside, and described encapsulated layer is arranged at the outside of described coil windings and described skeleton; Described coil windings adopts self-binding enamel wire.
As preferably, the line-spacing of described coil windings is 0.65～0.70 ㎜; Line-spacing the best of described coil windings is 0.68 ㎜.
The beneficial effects of the utility model are:
The utility model adopts self-binding enamel wire to replace the polyester enamelled wire of traditional divide-shut brake coil, and the enamelled wire temperature resistant grade rises to 180 ℃ by 130 ℃; Under 170～180 ℃ high temperature, the self-binding enamel wire of divide-shut brake coil described in the utility model can fuse and further play insulating effect, and the useful life of whole coil and reliability are improved; The self-binding enamel wire of divide-shut brake coil described in the utility model need not to soak electrical engineering insulation paint, shorten coil molding technique, improved production efficiency, exempted the pollution of insulating varnish to environment, avoided simultaneously the high energy consumption of insulating varnish baking needed, be conducive to energy-conservation and environmental protection.
Description of drawings

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, divide-shut brake coil described in the utility model comprises coil windings 1, skeleton 3 and encapsulated layer 2, and coil windings 1 is wound in the cavity in skeleton 3 outsides, and encapsulated layer 2 is arranged at the outside of coil windings 1 and skeleton 3; Coil windings 1 adopts self-binding enamel wire; The line-spacing of coil windings 1 is 0.68 ㎜.
Coil windings 1 needs strict control winding tension in the scope of 2.2 ± 0.3kgf in winding process; Threading speed is controlled in the scope of 800 ± 20r/min.
Coil windings 1 adopts self-binding enamel wire, and its temperature resistant grade rises to 180 ℃ by 130 ℃ of traditional polyester enamelled wire; Under 170～180 ℃ high temperature, self-binding enamel wire can fuse and further play insulating effect, and the useful life of whole coil and reliability are improved.
