Abstract
The invention discloses an overtemperature indication spacer, which comprises a metal spacer body, a heat conducting circular tube and a color signal indication strip. The overtemperature indication spacer has the advantage of simple structure, low cost, replaceable signal indication strip, and convenient and reliable installation and use.
Description
Technical field
The present invention relates to high voltage electric equipment electrically connecting clamp overtemperature indicating gasket, especially relate to the electrical connection of high voltage electric equipment, device clamp, parallel groove clamp, T-shaped wire clamp heating detection and instruction warning pad.
Background technology
There is a large amount of electrical connector in the equipment such as transformer station and ultra-high-tension power transmission line, when loose contact, joint area resistance increases, and when having electric current to pass through, will produce high temperature, if processing not in time, it is easy to cause security incident.Existing conventional means is to adopt temperature indicating patch and infrared thermometer and infrared imaging instrument to be monitored.But temperature indicating patch false alarm or come off after summer rainwater of being everlasting, brings much unnecessary work to overhaul of the equipments unit.Mobile infrared temperature measurer and infrared imaging instrument are due to relatively costly, it is impossible to be continuously monitored, and can only adopt the way of regular visit, and when patrolling and examining, load current is not necessarily maximum, and therefore Detection results is very undesirable.
Summary of the invention
Present invention aim at providing a kind of simple in construction, safe and convenient to use, the reliable overtemperature indicating gasket of temperature precise control.
For achieving the above object, the present invention takes following technical proposals:
A kind of overtemperature indicating gasket, it is characterised in that: include metallic gasket, heat conduction pipe, colour signal bar.The effective high heating rate metal of described metallic gasket and heat conduction garden is made.Described colour signal bar is made up of polymer shape memory material.
Described metallic gasket and heat conduction pipe are connected.Described multimedia message signal designation bar is installed and among heat conduction pipe.
The invention has the advantages that a kind of a kind of overtemperature indicating gasket of offer, simple in construction, with low cost, signal designation bar is replaceable, easy to install reliably.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
One overtemperature indicating gasket of the present invention as shown in Figure 1, including metallic gasket 1, heat conduction pipe 2, colour signal bar 3.Described metallic gasket 1 and heat conduction pipe 2 are connected with high heating rate metal.Colour signal bar 3 is made up of polymer shape memory material.Described multimedia message signal designation bar 3 is reducing cylinder, and its maximum gauge place is stuck in heat conduction pipe 2 top, and middle time major diameter, slightly larger than heat conduction pipe 2 internal diameter, tightly fills in heat conduction pipe 2, and bottom relatively carefully passes from heat conduction garden pipe 2.When electrical connector contact is good, temperature is lower than the critical temperature of polymer shape memory material, and do not deform contraction, it may be observed that from the colour signal bar 3 that heat conduction pipe 2 wears out.The critical temperature of polymer shape memory material is increased to over when electrical connector comes in contact temperature that is bad and that cause, colour signal bar 3 deforms contraction, heat conduction pipe 2 bottom is not it is observed that the colour signal bar 3 passed, and prompting tour personnel note, it is prevented that accident occurs.
Claims (5)
