A driving element for electrical equipment heating indicator, described driving element is that marmem is made; Be the planar spiral of metal loop around formation of width 0.5-5mm during described driving element normal temperature, described driving element is by after thermal deformation being the three-dimensional spirality longitudinally highly increased.
A preparation method for the driving element of electrical equipment heating indicator, comprises the following steps:
Step 1, by Ni-Ti-based shape memory alloy plate cutting or planar spiral blank wire rod being turned to required form;
Step 2, loads die casting by described planar spiral blank and fixes, and then at 600-700 DEG C, is incubated sizing in 10 minutes, the demoulding after cool to room temperature;
Step 3, the shaped element after step 2 being processed is incubated 30 minutes and carries out tempering at 400-600 DEG C, after cool to room temperature, prepares the driving element finished product of required form.
Technique effect: when application the present invention is connected with electrical equipment, when device temperature is elevated to setting high temperature values, driving element deforms, change into three-dimensional spirality, top cover is obviously separated with base, exposes base excircle simultaneously, demonstrate base color casing.When staff carries out equipment-patrolling according to equipment patrol system at ordinary times, can judge whether this monitoring point once overtemperature occurred according to the shape of indicator and color of shell, to ascertain the reason process potential safety hazard in time, the generation of minimizing accident.
Structure of the present invention is simple, and handling ease, does not affect structure and the use of equipment after installation.Indicator can do thinner by the present invention, and volume is less, is especially convenient at the relatively narrow and small environment of some installing spaces, or uses under the special condition of installing space shape, is applicable to environmental baseline widely.Obviously, the operation being convenient to application personnel is grasped, and can reuse, save use cost for normal temperature of the present invention and the difference of high temperature display state.The present invention is widely used, and the transformer station relevant to commercial production and resident living, transmission line of electricity, controller switching equipment etc. all can be installed and used.
