Abstract
The invention discloses an overheated alarm for electrical equipment heating, which comprises a fixed heat conducting bar with a connecting mechanism, wherein the fixed heat conducting bar is provided with two multilateral petaloid metal sheets; and the fixed heat conducting bar is connected to the electrical equipment through the connecting mechanism. In the invention, when the electrical arrangement temperature rises to a certain value, the fixed heat conducting bar connected with the electrical equipment thermally conducts the heat to the two metal sheets so that the two metal sheets deform from small to large, and an alarming pigment layer is shown outside because of the deformation, thereby being easily sawn.
Description
Technical field
The invention belongs to device temperature warning device technical field, particularly a kind of electrical equipment heating overheat alarm.
Background technology
In electrical production widely, in the electric equipment operation process, electrical equipment heating phenomenon is a ubiquitous physical phenomenon, particularly at transmission line of electricity, the transformer station of various electric pressures, the various public services place of factory and electricity consumption, in the electrical equipment of life residential electricity consumption, coupling part between each is electric, because the manufacturing process of electrical equipment, installation technology, the heating phenomenon that factors such as the size of power load and running environment cause often takes place, and electric heating is electric power safety production, the major safety risks of equipment stable operation, annual because the current device damage of electric heating, interruption of power supply, or even fire failure has all caused tremendous loss to enterprise, the discovering device share early of how preventing to generate heat is an important process in electrical production and the commercial production, prevention method commonly used now has: try warm wax disk(-sc) method, this method comes off easily voluntarily, causing when environment temperature is too high self to melt causes wrong report unreliable, the thermometric temperature is low excessively, nonrepeatability causes equipment pollution.The infrared laser thermometry costs an arm and a leg, and is unfavorable for popularizing using, and thermometric is inaccurate, and itself is measured error, and operative technique is strong, has shake that bigger error is just arranged slightly, and is more passive, needs to measure on time, and inconvenience is in time pinpointed the problems.
Summary of the invention
But the invention provides a kind of cost low, reliable, be convenient to install, do not destroy the reusable electrical equipment heating of former electrical equipment one-step installation overheat alarm.
A kind of electrical equipment heating overheat alarm comprises the fixedly heat conducting bar of being with bindiny mechanism, and polygon petal-shaped bimetallic strip is set on the described fixedly heat conducting bar, and described fixedly heat conducting bar leads to the structure of meeting sb. at the airport and is connected on the described electrical equipment.
Described bindiny mechanism is a bolt connecting mechanism.
The warning uvea is set on the described bimetallic strip.
When temperature being set being elevated to certain value, to bimetallic strip, change from small to big with the heat thermal conductance by bi-metal plate deformed electric for the fixedly heat conducting bar that is connected with electrical equipment in the present invention, and because of be out of shape the warning uvea is illustrated in outside, see easily.After the installation, the staff carries out equipment according to the equipment system of inspection tours at ordinary times and makes an inspection tour, and finds in time to handle after the alarm equipment alarm, reduces the generation of power outage or device damage accident.Cost of the present invention is low, produces in batches as forming, and cost can be reduced to the higher slightly price level of standard component at ordinary times, need not pay extra cost substantially.Automatically report to the police, need not safeguard especially.In time reliable, can not report by mistake.Reuse, consume less.Save cost, reduce accident rate.Be widely used, all can install and use, be convenient to install, do not destroy original equipment from transformer station, transmission line of electricity, controller switching equipment, commercial production, resident living.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1: a kind of electrical equipment heating overheat alarm, comprise the fixedly heat conducting bar 1 of being with bindiny mechanism, polygon petal-shaped bimetallic strip 2 is set on the described fixedly heat conducting bar 1, described fixedly heat conducting bar 1 leads to the structure 3 of meeting sb. at the airport and is connected on the described electrical equipment.Described bimetallic strip has Ni-Ti metal, Cu-Zn, Au-Cu or three-layer metal sheet such as CuZnAL, CuALNi metal material, and their characteristics are: amount of bow is big, plasticity height, shape before recovering more than the memory temperature.Described bindiny mechanism 3 is a bolt connecting mechanism.On the described bimetallic strip 2 the warning uvea is set.The fixedly heat conducting bar that electrical equipment connects when temperature being set being elevated to certain value, is given bimetallic strip with the heat thermal conductance electric, and bi-metal plate deformed is changed from small to big, and because of outside distortion is illustrated in the warning uvea, sees easily.Temperature is reduced to after the setting value, and the bimetallic strip of distortion recovers former structure again.
Claims (3)
1. an electrical equipment heating overheat alarm comprises the fixedly heat conducting bar of being with bindiny mechanism, and it is characterized in that: polygon petal-shaped bimetallic strip is set on the described fixedly heat conducting bar, and described fixedly heat conducting bar leads to the structure of meeting sb. at the airport and is connected on the described electrical equipment.
2. electrical equipment heating overheat alarm as claimed in claim 1, it is characterized in that: described bindiny mechanism is a bolt connecting mechanism.
