Description
Technical field
The utility model relates to a kind of contact box.
Background technology
Contact box is an important insulating element commonly used in 6～35kv high-tension switch cabinet, can directly have influence on each regional Electrical Safety, can cause large-area power-cuts even personal injury if any accident.Common contact box in use is prone to electric discharge phenomena, and long-time discharge can produce a large amount of aqueous vapors, and air dielectric humidity is increased, and has aggravated degree of discharge, can make insulating material aging in the course of time, punctures to cause security incident.Dynamic and static contact in the contact box causes the contact site temperature to raise owing to reasons such as cooperations very easily produce distortion or loose contact, for a long time overheatedly will cause security incident.
The utility model content
The purpose of the utility model is that a kind of contact box will be provided, and can produce warning when this contact box is overheated, and then can avoid because of the long-time overheated security incident that causes.
For achieving the above object; The technical scheme of the utility model is: a kind of contact box; Comprise the contact box body, be arranged on fixed contact installing hole and copper bar installing hole on the contact box body; Be provided with shielding blind hole cover in the contact box body of fixed contact installing hole and connection place of copper bar installing hole; Have through hole on the shielding blind hole jacket wall and be communicated with fixed contact installing hole and copper bar installing hole, overlap the fixing hole that is provided with fixing copper bar on the end face of Closed End to the fixed contact installing hole and the fixing fixed contact base of fixed contact in the shielding blind hole; On the contact box body, also be provided with thermal bulb, be provided with full skirt at the thermal bulb inwall of thermal bulb and contact box body link, be provided with temperature sensor in the other end of thermal bulb, temperature sensor and temperature alarm are electrically connected.
Further, be provided with the insulating protection sheet between said full skirt and the temperature sensor.
Compared with prior art, the contact box that the utility model provides has the temperature alarming function, has avoided the security incident because of long-time overheated appearance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1; A kind of contact box; Comprise the contact box body, be arranged on fixed contact installing hole 11 and copper bar installing hole 12 on the contact box body 1; Be provided with shielding blind hole cover 2 in the contact box body 1 of fixed contact installing hole 11 and 12 connections place of copper bar installing hole, the shielding blind hole is overlapped and is had through hole on 2 walls and be communicated with fixed contact installing hole 11 and copper bar installing hole 12, overlaps the fixing hole 21 that is provided with fixing copper bar on the end face of 2 Closed Ends to fixed contact installing hole 11 and the fixing fixed contact base 22 of fixed contact in the shielding blind hole; On contact box body 1, also be provided with thermal bulb 3, be provided with full skirt 4 at thermal bulb 3 inwalls of thermal bulb 3 and contact box body 1 link, be provided with temperature sensor 5 in the other end of thermal bulb 3, temperature sensor 5 is electrically connected with temperature alarm 6; Be provided with insulating protection sheet 7 between said full skirt 4 and the temperature sensor 5.
This contact box has the temperature alarming function, has avoided the security incident because of long-time overheated appearance.
All simple distortion of under the situation that does not break away from the utility model core, making or modification all fall into protection scope of the present invention.
