Description
[technical field]
This utility model relates to power distribution cabinet temperature-sensitive field of display devices, especially relates to a kind of power distribution cabinet safety management temperature-sensitive
Display device.
[background technology]
Low-voltage power distribution switch cabinet, is used for switching input and output and is connected by multistage bus bar copper row and is attached, even in its cabinet
The place of connecing all uses screw and compresses solid, it is ensured that its maximum contact face.But when there is production, workman's Tightening moment is inadequate, transport shake
Dynamic, screw is aging loosens, however it remains clamping torque causes loose contact not, generates heat when the biggest electric current passes through at this,
There is great Electrical Safety hidden danger, caused equipment fault, fire cases are really many, how to avoid copper bar junction because of mistake
There is equipment fault and fire in heat, also becomes the emphasis of concern.Passing distribution system copper bar temperature detection is simply used infrared
The junction that temperature measurer regular visit, particularly components and parts block, it is more difficult to accomplish to measure one by one, leave potential faults.
[summary of the invention]
This utility model aims to solve the problem that the problems referred to above and provides one can point out early warning according to the temperature variable color voluntarily that differs
Power distribution cabinet safety management temperature-sensitive display device.
For achieving the above object, a kind of power distribution cabinet safety management temperature-sensitive display device of the present utility model, including two pieces of phases
Contact the copper bar 10 connected mutually and for fixing the fixture 20 of copper bar 10, the junction of copper bar 10 and fixture 20 outer cover
Being connected to heat discoloration silica gel sheath 30, described heat discoloration silica gel sheath 30 shows green, exceedes when temperature is 0-50 degree Celsius
50 degrees Celsius of display yellow.
Further, described fixture 20 is nut 21 and screw rod 22, and providing holes 11 on described copper bar 10 is described
Screw rod 22 is tightened fixing with nut 21 behind hole 11.
Further, described heat discoloration silica gel sheath 30 is arranged to cuboid, cuboid arranges one and passes through from top
Wearing the screw hole 31 of bottom, adjacent two sides hollow out, and form a groove 32, and described groove 32 is by the junction of copper bar 10
In being wrapped in fixture 20, described screw rod 22 passes in screw hole 31.
Contribution of the present utility model there are provided a kind of power distribution cabinet safety management temperature-sensitive display device, passes through temperature discoloring
Alarm shows, makes power distribution cabinet copper bar circuit and switching component more safely run.Effectively evade fire, fault occurs, greatly
Improve safety in production reliability.

Cross 50 degrees Celsius of display yellow, when temperature is too high, during display yellow, can find easily checking when and get rid of hidden
Suffer from.
Embodiment 2
As shown in Fig. 1,3,4, the fixed form of the present embodiment is perfect fixture 20, described fixture 20 is nut 21
With screw rod 22, providing holes 11 on described copper bar 10, described screw rod 22 is tightened fixing with nut 21 behind hole 11.
Embodiment 3
As shown in Fig. 1,2,4, the structure of the present embodiment is perfect heat discoloration silica gel sheath 30 and fixed form, described sense
Temperature variable color silica gel sheath 30 be arranged to cuboid, cuboid is arranged one run through from top bottom screw hole 31, adjacent two
Side hollows out, and forms a groove 32, and junction and the fixture 20 of copper bar 10 are wrapped in interior by described groove 32, described
Screw rod 22 passes in screw hole 31.This kind of flexible structure, simply, installation and removal are convenient, it is simple to promote the use of.
Although this utility model being disclosed by above example, but protection domain of the present utility model not office
Being limited to this, under conditions of conceiving without departing from this utility model, the deformation of being done above each component, replacement etc. all will fall into
