Abstract
The utility model relates to an infrared temperature monitoring device for a switchgear. The infrared temperature monitoring device comprises a data processing unit and a temperature acquisition unit, and is characterized in that the temperature acquisition unit is an infrared temperature sensor and the signal output terminal of the temperature acquisition unit is connected with the data processing unit in an electric signal manner. The infrared temperature sensor is a non-contact infrared temperature probe, with a temperature measuring scope from 0 to 300 DEG C. The infrared temperature monitoring device for a switchgear also comprises a voice alarm unit and a display unit. The voice alarm unit and the display unit are respectively connected with the signal output terminal of the data processing unit in an electric signal manner. The non-contact probe is adopted for temperature measurement by the infrared temperature monitoring device for a switchgear, thereby effectively avoiding the adverse influence caused by the contact with high voltage, and greatly improving the reliability of temperature monitoring.
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 and uses infrared temperature monitoring device.
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.Present most of on-line temperature monitoring is a contact type temperature sensor, and receives the influence of high pressure bigger as the sensor of core component, the on-line monitoring poor reliability; And present on-line monitoring is used switch cubicle autonomous induction power supply, and this power supply prerequisite is a switch bigger working current is arranged, otherwise working power is bad, causes temperature measurement error bigger.
The utility model content
To above-mentioned defective, the purpose of the utility model provides a kind of switch cubicle and uses infrared temperature monitoring device, adopts contact type temperature sensor to solve existing switch cubicle, receives the influence of high pressure bigger, the technical matters of on-line monitoring poor reliability.
For realizing above-mentioned purpose, the technical scheme below the utility model has adopted:
A kind of switch cubicle is used infrared temperature monitoring device, comprises data processing unit and temperature collecting cell, it is characterized in that: described temperature collecting cell is an infrared temperature sensor, and its signal output part is connected with the data processing unit electric signal.
Described infrared temperature sensor is contactless infrared temperature probe, and its temperature measurement range is 0-300 ℃.
Use infrared temperature monitoring device according to the described switch cubicle of the utility model preferred embodiment, also comprise audible alarm unit and display unit, described audible alarm unit is connected with the signal output part electric signal of data processing unit respectively with display unit.
Owing to adopted above technical characterictic; Make the utility model than prior art; Have following advantage and good effect: the utility model switch cubicle adopts contactless probe thermometric with infrared temperature monitoring device; Effectively avoid contacting the harmful effect that brings, improve the reliability of temperature monitoring greatly with high pressure.
Description of drawings
Fig. 1 is the electrical block diagram 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 is used infrared temperature monitoring device, and temperature collecting cell is an infrared temperature sensor, and its signal output part is connected with the data processing unit electric signal.Described infrared temperature sensor is contactless infrared temperature probe, and its temperature measurement range is 0-300 ℃.The audible alarm unit is connected with the signal output part electric signal of data processing unit respectively with display unit.
During work; Contactless infrared temperature probe obtains the real time temperature signal, and is transferred to data processing unit near the temperature of contact place turnover busbar; The simultaneous temperature value is shown by display unit; Data processing unit judges that whether the value of dut temperature exceeds the warning preset value, if exceed preset value, is then given the alarm by the audible alarm unit.Can also can be connected with the pulpit computer through the interface of data processing unit, realize remote monitoring.
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.
