The side wall of the two transverse sides of the limit frame is provided with a guide runner which is matched with a guide pole arranged on the U-shaped copper billet. The position near the U-shaped copper billet on the placode of the auxiliary radiating flanges is provided with a temperature controller which is connected to a relay through a circuit board; when the temperature exceeds the preset value, the temperature controller touches the relay to be in motion, so a blower is activated to cool the coils of the voltage stabilizer or stop working temporarily to protect the voltage stabilizer.
Description
Technical field
The utility model relates to a kind of parts of pressurizer, relates in particular to a kind of novel brush assembly of electric that is used for pressurizer.
Background technology
Pressurizer has very big application at present, mostly is to adopt copper-graphite composite electric brush, and adopts the interphase reactor system, can solve turn-to-turn short circuit electric current and big electric current admittance problem.Pressurizer requires very high to the craft precision of brush itself and pressurizer coil, increase the contact pressure of carbon brush sheet and pressurizer coil but mostly existing brush assembly of electric is the design cylindrical spring, because in the pressurizer course of work, when brush assembly of electric constantly moves around, also suitably regulate up and down, to keep the contact pressure between carbon brush sheet and the pressurizer coil, cylindrical spring is when being compressed to certain limit, be difficult to keep its linear elastic force relation, also just be difficult to keep the contact pressure between carbon brush sheet and the pressurizer coil this moment, it is unstable to occur contact easily, problems such as short circuit and big electric current admittance influence coil useful life.Pressurizer produces a large amount of heats on the copper billet when work, need heat radiation in time, and mostly existing brush assembly of electric is to be provided with above the brush holder fin, sometimes is difficult in time dissipate unnecessary heat.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of novel brush assembly of electric that is used for pressurizer is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of novel brush assembly of electric that is used for pressurizer, comprise brush holder, main fin is arranged in the extension of described brush holder head both sides, secondary fin is set above the main fin, the substrate of main fin extension downwards is provided with limitting casing, U type copper billet is set in the limitting casing, in the opening that U type copper billet makes progress the tower spring is set, the two side ends of U type copper billet is fixed on the substrate of secondary fin, and the lower end of U type copper billet is provided with the carbon brush sheet.
As preferably, the top of described limitting casing is provided with the tower spring seat of honour, and the bottom at the tower spring seat of honour is provided with sleeve column, the thin end phase configuration of sleeve column and tower spring.
As preferably, on the sidewall of described limitting casing both lateral sides guide chute is set, the guiding mast phase configuration that is provided with on guide chute and the U type copper billet.
As preferably, near U type copper billet place thermostat is set on the substrate of described secondary fin, thermostat is connected to relay by wiring board, and the control blower fan starts and cools off the pressurizer coil, or temporarily quits work, with the protection pressurizer.
Therefore, the utility model is simple in structure, and is reasonable in design; Brush holder head both sides are extended into main fin and secondary fin is set above the main fin, and radiating effect improves greatly, can in time dissipate unnecessary heat; Be provided with the tower spring in the opening that U type copper billet makes progress, utilize the linear elastic force relation of tower spring, when brush assembly of electric constantly moves around, can keep the contact pressure between carbon brush and the pressurizer coil, contact pressure between carbon brush and the pressurizer coil is comparatively stable, be not easy to occur phenomenons such as short circuit and big electric current admittance, and then can prolong whole useful life.
