Abstract
A novel valve for an alternating current metal-enclosed switchgear comprises a first guide bar and a second guide bar, wherein a first guide sleeve is arranged on the first guide bar in a sleeved mode, and a second guide sleeve is arranged on the second guide bar in a sleeved mode. The valve further comprises a valve board, the valve board comprises an insulating board made of insulating materials, and a metal conducting layer is arranged on one side of the insulating board and faces to the front door of the alternating current metal-enclosed switchgear. Two sides of the valve board are respectively and fixedly connected with the first guide sleeve and the second guide sleeve. The metal conducting layer is arranged on one side where personnel is easy to contact of the valve board, the valve board is connected with the first guide sleeve and the second guide sleeve so that the valve board is reliably connected to the ground, purpose of eliminating of dangerous electrostatic charge is achieved, while insulating property of the insulating board made of the insulating materials is not affected by processing techniques, so that insulating reliability is high.
Description
(1) technical field
The utility model relates to a kind of ac metal closing switch gear and uses valve.
(2) background technology
Along with the popularization of country to strong power grid construction, to power supply reliability and fail safe require increasingly highly, the requirement of fail safe of switching devices simultaneously and reliability is also in raising.Valve is one of very important parts on the ac metal closing switch gear, and its reliability and fail safe are extremely important to the stable operation of electrical network and plant maintenance personnel's safety guarantee.At present, the valve of ac metal closing switch gear adopts metallic plate spraying epoxy powder or the directly design of use insulation board usually.Make the normally thin steel plate of metallic plate of valve, because the volume of metallic plate is big, in the process of dusty spray; The deflection deformation of metallic plate is big, and it is inhomogeneous that epoxy powder is adhered to, and the epoxy layer thickness dispersiveness after the moulding is bigger; Rate of finished products is not high, unsuitable batch machining; The valve design of simple insulation board material; Because valve plays the isolated high-voltage conductor in a position therein; Can be in valve surface accumulative total electrostatic charge, during ac metal closing switch gear is safeguarded, there is potential potential safety hazard in plant maintenance personnel's personal safety.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing ac metal closing switch gear with valve; The utility model provides a kind of function of existing insulation protection; The electrostatic charge that can eliminate danger again, the ac metal closing switch gear that meets the requirement of switching devices high reliability, high security is used novel valve.
The technical scheme that the utility model solves its technical problem is: a kind of ac metal closing switch gear is used novel valve; Comprise first guide post and second guide post; Be arranged with first fairlead on described first guide post, be arranged with second fairlead on described second guide post;
Also comprise valve plate, described valve plate comprises the insulation board that insulating material is processed, and the one side of described insulation board is provided with metal conducting layer, and described metal conducting layer is towards the main entrance of ac metal closing switch gear;
The both sides of described valve plate are affixed with described first fairlead and second fairlead respectively.
Further, be connected through metal fastenings between described valve plate and described first fairlead, second fairlead.
Further, described metal conducting layer is the metal powder layer that is sprayed on the insulation board.
The beneficial effect of the utility model is: the one side that the personnel of valve plate are easy to contact is established metal conducting layer; Valve plate is connected with first fairlead, second fairlead; Make its reliable ground; Reach the purpose of the electrostatic charge that eliminates danger, and the insulation board insulation property that insulating material is processed do not receive the influence of processing technology, insulating reliability is high.
(4) description of drawings
Fig. 1 is the structural representation of the utility model.
(5) embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
With reference to Fig. 1, a kind of ac metal closing switch gear is used novel valve, comprises first guide post 1 and second guide post 2, is arranged with first fairlead 3 on described first guide post 1, is arranged with second fairlead 4 on described second guide post 2.
Also comprise valve plate 5; Described valve plate 5 comprises the insulation board that insulating material is processed; The one side of described insulation board is provided with metal conducting layer; Described metal conducting layer is towards the main entrance of ac metal closing switch gear, promptly is processed with the one side that the surface of metal conducting layer is easy to contact near personnel on the valve.If it is multiple that the method for metal conducting layer has, be the metal powder layer that is sprayed on the insulation board, perhaps electrodeposited coating or mosaic coating etc. like metal conducting layer.
The both sides of described valve plate 5 are affixed with described first fairlead 3 and second fairlead 4 respectively.Be connected through metal fastenings such as screw between valve plate 5 described in the present embodiment and described first fairlead 3, second fairlead 4.
In the utility model; The personnel of valve plate are easy to contact is processed with metal conducting layer; Valve plate is connected with first fairlead 3, second fairlead 4, makes its reliable ground, reaches the purpose of the electrostatic charge that eliminates danger; And the insulation board insulation property that insulating material is processed do not receive the influence of processing technology, and insulating reliability is high.
Claims (3)
