Abstract
The invention discloses an overheating alarm for heat emission of an electrical device. The overheating alarm for heat emission of the electrical device comprises a fixed heat conducting bar with a connecting mechanism, wherein multilateral petal-shaped bimetallic strips are arranged on the fixed heat conducting bar, and the fixed heat conducting bar is connected to the electrical device through the connecting mechanism. When the temperature of the electrical device rises to a set value, the fixed heat conducting bar connected with the electrical device transfers heat to the bimetallic strips in a heat conductance mode, the bimetallic strips deform and become from small to big, and alarm pigment layers are shown outwards due to the fact that deformation happens, and can be easily seen.
Description
Technical field
The invention belongs to device temperature warning device technical field, particularly a kind of overheated alarm for electrical equipment heating.
Background technology
In electrical production widely, in the electric equipment operation process, the electrical equipment fever phenomenon is a ubiquitous physical phenomenon, particularly at transmission line of electricity, the transformer station of various electric pressures, the various Public places 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 fever phenomenon that the factors such as the size of power load and running environment cause often occurs, 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 huge 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 has now: try warm wax disk(-sc) method, the easy self falling of the method, causing when environment temperature is too high self to melt causes wrong report unreliable, the thermometric temperature is excessively low, nonrepeatability causes equipment pollution.The infrared laser thermometry, expensive, be unfavorable for popularizing and use, thermometric is inaccurate, and itself is measured error, and operative technique is strong, slightly has shake that larger error is just arranged, 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 overheated alarm for electrical equipment heating of former electrical equipment one-step installation.
A kind of overheated alarm for electrical equipment heating comprises the fixedly heat conducting bar 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 connection mechanism and is connected on the described electrical equipment.
Described bindiny mechanism is bolt connecting mechanism.
The warning uvea is set on the described bimetallic strip.
The fixedly heat conducting bar that is connected with electrical equipment in the present invention is when electric set temperature is elevated to certain value, and to bimetallic strip, bi-metal plate deformed is changed from small to big with the heat thermal conductance, and because of be out of shape the warning uvea is illustrated in outside, see easily.After the installation, the staff carries out equipment-patrolling according to equipment patrol system at ordinary times, finds in time to process after the alarm equipment alarm, reduces the generation of power outage or device damage accident.Cost of the present invention is low, and as forming batch production, cost can be down to the at ordinary times slightly higher price level of standard component, substantially need not pay extra cost.Automatic alarm need not be safeguarded 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 from transformer station, transmission line of electricity, controller switching equipment, commercial production, resident living, be convenient to install, do not destroy original equipment.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1: a kind of overheated alarm for electrical equipment heating, comprise the fixedly heat conducting bar 1 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 connection mechanism 3 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 large, and plasticity is high, shape before recovering more than the memory temperature.Described bindiny mechanism 3 is bolt connecting mechanism.On the described bimetallic strip 2 the warning uvea is set.The fixedly heat conducting bar that electrical equipment connects is when electric set temperature is elevated to certain value, and to bimetallic strip, bi-metal plate deformed is changed from small to big with the heat thermal conductance, 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 again former structure.
Claims (1)
