Abstract

The utility model provides a contact box with transparent windows. The contact box comprises a bus, a box shell, an inlay hole, the transparent windows, and a magnifier. The box shell is integrally sealed by rubber. The inlay hole is located on the box shell. The bus is mounted in the inlay hole. The transparent windows are mounted on the box shell. The magnifier is mounted in the box shell. The transparent windows are formed by inlaying insulated transparent materials in the box shell. The transparent windows of the utility model are made of the insulated materials so that the addition of the transparent windows does not damage the insulating property of the contact box. Through the magnifier and the transparent windows, the contact situation in the bus can be observed directly and thus, the security of the contact box can be improved.

Description

A kind of contact box with transparent window

Technical field

the utility model relates to contact box and manufactures field, relates in particular to a kind of contact box with transparent window.

Background technology

contact box is insulating element conventional in high-tension switch cabinet, middle-placed switch cabinet.For contact box, bus contacts with fixed contact, if loose contact or jagged etc. can form the enhancing of local electric field, in aerial discharge, can cause the destruction of contact box insulation, thereby cause serious accident.Existing contact box is not transparent, therefore, cannot observe directly inner situation.

Utility model content

for existing technical problem, the utility model provides a kind of contact box with transparent window, is guaranteeing under the prerequisite of insulating properties the contact situation that can directly observe bus inside by transparent window, the fail safe that improves contact box.Technical solution adopted in the utility model is, a kind of contact box with transparent window, comprises bus, box shell, inlaid hole, transparent window, magnifying glass, wherein, on box shell, transparent window is installed, and magnifying glass is installed on the inside of box shell; The whole employing of box shell rubber seal, inlaid hole is positioned on box shell, and bus is arranged in inlaid hole; Transparent window adopts the transparent material of insulation to be embedded on box shell.

transparent window of the present utility model is insulating material, increases the insulating properties that transparent window does not destroy contact box, the situation that contacts that can directly observe bus inside with transparent window by magnifying glass, the fail safe that improves contact box.

Accompanying drawing explanation

fig. 1 is structural representation of the present utility model.

in figure: 1 bus, 2 box shells, 3 inlaid holes, 4 transparent windows, 5 magnifying glasses.

Embodiment

below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

fig. 1 is structural representation of the present utility model, comprises bus 1, box shell 2, inlaid hole 3, transparent window 4, magnifying glass 5, wherein, the whole employing rubber seal of box shell 2, inlaid hole 3 is positioned on box shell 2, and bus 1 is arranged in inlaid hole 3; Transparent window 4 is installed on box shell 2, and magnifying glass 5 is installed on the inside of box shell 2; Transparent window 4 adopts the transparent material of insulation to be embedded on box shell 2.Transparent window 4 of the present utility model is insulating material, increases the insulating properties that transparent window 4 does not destroy contact box, the situation that contacts that can directly observe bus 1 inside with transparent window 4 by magnifying glass 5, the fail safe that improves contact box.
