Abstract
The present utility model relates to a switch cabinet temperature state acquisition device. A thermopile sensor is employed as a temperature sensor, the power supply end of the sensor is connected with an output end of a current transformer, and an inductance loop of the current transformer is sleeved outside an insulation sleeve of a switch cabinet high voltage inlet wire. The temperature sensor is arranged on the wiring position inside the switch cabinet. In the switch cabinet temperature state acquisition device, the current transformer is employed as the front end power supply of the temperature sensor, and the temperature sensor is used for monitoring the temperature of the wiring position inside the switch cabinet, especially the bus electrical connecting position in real time. Compared with the infrared ray detection method, the device is good in reliability.
Description
Technical field
The utility model relates to the correlative technology field of switch cubicle monitoring, is specifically related to a kind of switch cubicle state of temperature harvester.
Background technology
Nowadays oneself uses the switch cubicle of high load capacity in a large number in electrical network.And the over-heat inside phenomenon of switch cubicle has become the FAQs of switch cubicle in using, because the leakproofness of switch cabinet, in the heavier area of some loads, has the temperature rise of the switch cubicle problem that exceeds standard.The temperature rise of switch cubicle exceeds standard, and directly influences the safe and stable operation of equipment, and problems of excessive heat is a constantly process of development, if do not control, degree of superheat is aggravation constantly, and to the performance of insulating part and produce very big influence equipment life.Because heat generating spot is in sealed cabinet, operating cabinet gate inhibition only opens, and the operator on duty can't find the heating defective through normal supervision means.Generating heat, joint can redden even fuse when serious, directly causes industrial accident.According to statistics, electric system has an accident has considerable part relevant with problems of excessive heat in the reason, and contact, the connector temperature of therefore adopt an effective measure monitoring high-voltage switch gear, high voltage bus and high-tension cable are the problems that electric system need solve.In order to monitor the heating situation of inner each parts of switch cubicle in real time, assurance equipment normally moves, and reduces accident rate, is badly in need of switch cubicle is transformed, and installs temperature measuring equipment additional.
Because the development of sensing technology and microprocessing; Can carry out continuum of states to operating power equipment detects; At any time record the information that status of equipment changes, carry out after the analyzing and processing state of insulation being made diagnosis, confirm maintenance program according to diagnostic result; Accomplish to keep in repair targetedly, i.e. state maintenance.Yet the reliability of the infrared temperature sensor that existing switch cubicle uses is lower, is subject to the influence of outside various factors.
The utility model content
To above-mentioned defective, the purpose of the utility model provides a kind of switch cubicle state of temperature harvester, and is lower with the reliability that solves the employed infrared temperature sensor of existing switch cubicle, is subject to the technical matters that outside various factors influences.
For realizing above-mentioned purpose, the technical scheme below the utility model has adopted:
A kind of switch cubicle state of temperature harvester, its temperature sensor adopts thermopile sensor, and the probe power end is connected with the output terminal of a current transformer, and the inductance loop of described current transformer is sheathed on the insulating sleeve of switch cubicle high pressure inlet wire.Described temperature sensor is arranged at wiring place in the switch cubicle.
Owing to adopted above technical characterictic; Make the utility model than prior art; Have following advantage and good effect: the described switch cubicle state of temperature of the utility model harvester adopts the front end power supply of current transformer as temperature sensor, and temperature sensor is to wiring place in the switch cubicle, and especially bus electrical connection place temperature is monitored in real time; With respect to the infrared detection method, reliability is better.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
For ease of understanding, the preferred embodiment of the utility model is done being described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1; A kind of switch cubicle state of temperature harvester; Temperature sensor 1 adopts thermopile sensor, and sensor 1 power end is connected with the output terminal of a current transformer, and the inductance loop 2 of described current transformer is sheathed on the insulating sleeve 3 of switch cubicle high pressure inlet wire.Temperature sensor 1 is arranged at wiring place in the switch cubicle.
During work, current transformer is as the front end power supply of temperature sensor 1, and the output signal of temperature sensor 1 warp one signal amplification circuit 4 transfers to the temperature detection signal input end of a central control unit 5, to realize the real-time collection of temperature signal.
More than disclosed only be the preferred embodiment of the utility model; But be not to be used for limiting itself, anyly have the knack of those skilled in the art, under the situation of the utility model spiritual connotation; The equalization of being done changes and changes, and all should drop in the protection domain of the utility model.
