Thermometric mode is in the market divided into following five kinds of thermometric modes, and these five kinds of thermometric modes respectively have quality, see the following form:
Wireless temperature measurement system can carry out Real-Time Monitoring to the joint of the high pressure high-current equipments such as bus bar, disconnector, switch cubicle, ring main unit, isolating switch, contact, the tactile spot temperature such as wall, line.Operation maintenance personnel scene and remote monitoring center is facilitated to grasp field apparatus ruuning situation.
Traditional thermometric mode, as band wire can not meet enclosed environment and high-voltage large current occasion, it is large to there is deviation in infrared measurement of temperature, the problems such as efficiency is low.Operating electrical equipment is usually operated at high voltage and current state, and some defect existed in equipment can cause the abnormal temperature of part of appliance to raise.Cause the vicious cycle of temperature and contact resistance value, finally may cause the security incidents such as equipment burning, blast.It is a vicious cycle that contact temperature raises; High-tension switch cabinet is wanted to bear the working current being up to 5000A usually; Equipment is in During Process of Long-term Operation, and the tie points such as the contact of switch and bus connection are because of aging or contact resistance is excessive and generate heat and form vicious cycle; Have exposed high pressure in switch cubicle, space-closed is narrow and small, thermometric of cannot manually patrolling.
For a long time, high-tension apparatus joint area running temperature is difficult to monitoring, this is because these positions all have exposed high pressure, common thermometry can not use because solving High-Voltage Insulation problem.
Utility model content
For above-mentioned prior art Problems existing, the purpose of this utility model be to provide a kind of easy for installation, get good electrical property, the passive and wireless temperature probe that induced power own is little, anti-interference is good.For realizing this object, the utility model adopts following technical scheme:
A kind of passive and wireless temperature probe, comprises housing, wireless temperature measure module, coil; Described housing comprises upper shell and lower house; Described wireless temperature measure module is connected with control panel, described control panel is provided with signal acquisition module and wireless transmitter module; Described control panel and coil are located in described lower house, and described wireless temperature measure module stretches out outside described housing.This passive wireless temperature measuring device radiowave carries out data information transfer, sensor is arranged on high-tension apparatus joint area, and radio contact between receiving trap, therefore this system fundamentally solves the difficult problem that high-tension apparatus joint area running temperature is not easily monitored.Wireless transmission method is adopted to have high reliability and security.
Further, be provided with barricade in described lower house, described barricade is divided into two cavitys lower house, and one of them cavity is for placing control panel, and another cavity is for placing coil.
Further, described coil for there being shaped framework coil, around on skeleton.
Further, described wireless temperature measure module adopts magnetically soft alloy material to make.
Further, described control panel is provided with protection circuit.
Further, described control panel is provided with radome, and described radome adopts magnetically soft alloy material to make.
Further, described housing adopts high-temperature insulation material to make.Insulation and electromagnetism interference particularly in high voltage power transmisson system monitoring, are the extremely crucial problem of often encountering in electric system.In current electric system towards in more than 500kV UHV (ultra-high voltage), Large Copacity development, the running temperature monitoring of High voltage power supply equipment is particularly important, and wireless temperature measurement sensing technology has become its best solution.
Further, the dual-side on described upper shell is respectively provided with 2 ears.
Use this passive and wireless temperature probe can be installed on every platform high-voltage switch gear and busbar joint, system disposition standard communication interface, can networking operation, pass through host computer, the data of high-tension switch gear running temperature can be recorded, for the maintenance of high-tension apparatus provides foundation, achieve the Predictive Maintenance of equipment failure.
To compare prior art, the beneficial effect that the utility model has:
(1) CT power taking pattern, function is more perfect, carries out induction power taking by the primary current that contact arm or busbar flow through, superpower power taking performance, without work blind spot; As long as contact of breaker or switch cabinet busbar have 4A or 9A primary current that passive module just can be allowed normally to work.
(2) adopt two tie-type structure, install more convenient;
(3) passive and wireless temperature measurement module size is little, and mounting means is convenient, is applicable to contact wall and the busbar of various sizes, can be arranged on inside contact arm sleeve pipe or outside, can be arranged on the various position of busbar, have more selection, fast easier for installation.
(4) inductive energy is little, and stability is high; The power that inside modules senses from primary current is from the 80mW of 0.4mW to the 5000A of 3A, and the power sensed due to itself is little, does not need to go to consume how many energy by protection circuit, more stable; Shielding construction designs, and anti-interference is good;
(5) add radome and protection circuit, the interference that burst of pulses and surge bring can be tackled easily; New alloy materials application is little from heat production;
(6) wireless temperature measure module, adopt magnetically soft alloy material, heat production is very little, under the big current of 5000A on monitoring point without any impact, be different from traditional silicon steel disc, the energy got is very high, and heat production is very serious, can increase the weight of the temperature of monitoring point.
