Description
Technical field
The present invention relates to field of electrical equipment more particularly to a kind of temperature-sensitive instruction nuts.
Background technology
As defeated, change, controller switching equipment increase, apparatus connecting unit position is increasingly complicated various, because of running environment load variations, applies
The factors such as work technique influence, and power equipment connecting portion easily forms local pyrexia high temperature safe hidden danger, and power equipment quantity
Numerous, transmission line of electricity length, be not easy to find without professional equipment to detection connecting portion fever high temperature and waste larger manpower,
Material resources, once occurrence of equipment will cause large area blackout, loss is huge because of the high temperature damage accident that generates heat.And power equipment
Large number of, connection is longer, how to prevent fever early discovering device share be in power generation and industrial production one
Item important process.
Existing frequently-used prevention method has：The warm wax disk(-sc) method of 1 examination, this method easily voluntarily come off, are made when environment temperature is excessively high
It is unreliable to cause to report by mistake into itself thawing, and thermometric temperature is too low, and nonrepeatability causes equipment pollution.2 cable connectors are tinted
Paint, coats colored paint at cable connector, the situation of fever is then judged by observing the color change of phase colored paint, when phase colored paint
Darken, coat of paint split illustrates connector oneself fever.But the color of phase colored paint changes less sometimes, it is easy to cause to judge by accident
It is disconnected, so applying the fewer use of method of colored paint.3 infrared laser thermometry, it is expensive, it is unfavorable for universal use, thermometric is not
Accurately, itself, which is measured, error, and operating technology is strong, and slightly shaking just has larger error, relatively more passive, need to survey on time
Amount, inconvenience are pinpointed the problems in time.Therefore, temperature detection simple and effective in this way and warning device there is no to apply in power train at present
In system.
Invention content
Goal of the invention：The present invention is to solve the above problems, provide a kind of temperature-sensitive instruction nut.
Technical solution：The present invention provides a kind of temperature-sensitive instruction nut, including pedestal, temperature-sensing element and showing rod；The base

As a preferred embodiment of the present invention, the instruction column outer wall and pedestal appearance face color difference.
As a preferred embodiment of the present invention, lead is provided in the storage tank, the temperature-sensing element is sheathed on
On the outside of the lead.
Technique effect：The present invention provide a kind of low cost, it is reliable, simple in structure, do not destroy former electrical equipment, can one
It is secondary that the electrical equipment fever indicator reused again is installed.Pedestal of the present invention is equipped with threaded hole, in use, spiral shell can be screwed in
Bolt tail portion or the place that monitoring temperature is needed using magnet or be adhesive in.Work as equipment when being connect using the present invention with electrical equipment
When temperature is increased to product setting value, temperature-sensing element generates deformation, and showing rod bounces, and exposes colored outer wall.Staff according to
Equipment patrol system usually carries out equipment-patrolling, it is found that deformation instruction can be thought overtemperature once occurs at this, to find out original
Cause with timely processing, can reduce the generation of power outage or equipment damage accident.
The configuration of the present invention is simple, instruction is apparent, handling ease, can be reused with mass production applications；Simultaneously save into
This, reduces accident rate；And it is widely used, from substation, transmission line of electricity, controller switching equipment, industrial production to resident living
It can all install and use.The present invention is easily installed, and does not destroy original equipment.The original deformed upon using marmem temperature-sensitive
Reason, can monitor the temperature of transmission line of electricity contact or electrical equipment in real time, if the temperature monitored presets phase more than it
When becoming alarm temperature, then police instruction column bounces, and exposes colored outer wall, is found in time convenient for tour personnel, so as to grasp transmission of electricity
The variation of line contacts temperature avoids the generation of accident, eliminates the security risk of system operation, ensure that system equipment just
Often operation.
