Abstract
The utility model relates to a protective cover for voltage-current mutual inductors. At present, binding posts of inductors for metering are denuded at outside, so the fraudulent use of electricity can be easily carried out. The utility model develops a protective cover which is provided with a sealing device, and the binding posts of the inductors can be sealed by the utility model; so the utility model can effectively prevent or discover the behaviors of the fraudulent use of the electricity.
Description
The utility model is a kind of electrical installation, promptly a kind of voltage current transformer protective cover.
Present electricity distributing and metering device adopts metering electric energy meter and voltage, current transformer to be used more.Because of the binding post of instrument transformer all exposes outside, the people happens occasionally for the stealing case, and difficult the discovery.
The purpose of this utility model is a kind of voltage, current transformer protective cover that can prevent and find stealing of development.
Above-mentioned purpose is realized by following technical scheme: develop a kind of instrument transformer protective cover, be characterized in, said protective cover is a housing that can be closed the instrument transformer binding post.
Said housing can be made of lower casing and lid loam cake in the above.
Connection part between the lower casing of said loam cake can be provided with sealing device.
Said protective cover also can by can interconnective left shell and right shell body constitute.
Connection part between said left shell and the right shell body also can be provided with sealing device.
Said protective cover also can be a housing that has sealing device.
The protective cover that adopts such scheme to make can be with the wiring position sealing of instrument transformer, because of being provided with sealing device.So just can find and avoid the generation of stealing accident effectively.
Introduce three kinds of embodiment below in conjunction with accompanying drawing:
Fig. 1 is the front view of protective cover A-A section, and Fig. 2 is its vertical view.
Fig. 3 is the front view of second kind of embodiment, and Fig. 4 is its vertical view, and Fig. 5 is its left view.
Fig. 6 is the front view of the third embodiment, and Fig. 7 is its vertical view.
Have among the figure: loam cake 1, lower casing 2, screw 3, left shell 4, right shell body 5, protective cover 6.
First kind of embodiment:
By Fig. 1,2 as seen, loam cake 1, lower casing 2, screw 3.Lower casing 2 is enclosed within the instrument transformer bottom during use, and loam cake 1 covers on lower casing 2, and is with screw 3 that loam cake and lower casing is fastening.The aperture that then the lead sealing line is successively passed screw 3 and loam cake 1 and lower casing 2 seals pressure then and gets final product.
Second kind of embodiment:
By visible left shell 4, right shell body 5 and screw 3 among Fig. 3,4,5.Left and right two housings cover on the instrument transformer relatively during use, and are with screw 3 that it is fastening.Then the lead sealing line is passed left and right housing and the aperture above the screw respectively, press seal gets final product.
The third embodiment:
By visible protective cover 6 among Fig. 6,7, will penetrate from the protective cover outside through its bottom square hole from the lead that electric energy meter attracts during use, be attempted by on the instrument transformer.Then shielding cover on instrument transformer, main traverse line is stuck in the big hole of protective cover.Two small sircle hole press seals that reusable lead envelope line passes respectively on the big hole limit get final product.
