Description
Technical field
The utility model belongs to insulating plug, especially a kind of thermometric insulating plug.
Background technology
In recent years, along with the development and improvement of electric network composition, the construction of power circuit had obtained significant progress, and the distribution of electric complete cabinet (cable distribution box, loop-network switch cabinet etc.) is also more and more wider.It is widely used in the distribution substation and box-type substation of the load centers such as Urban Residential District, skyscraper, large public building, factory and enterprise.Electric complete cabinet is in long-term use procedure, because ageing equipment, or conductor contact is bad, can cause the contact resistance of cable junction to become large, and temperature raises; Power load is excessive, can cause that also temperature raises, and abovely all can cause equipment failure, outage, even the security incident such as blast.Existing thermometry can't be measured it: the sealed insulation excellent heat insulating performance of joint, outside can't thermometrics, can't increase temperature measuring equipment simultaneously in the assemblage gap of joint.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of temperature that can monitor for a long time electric complete cabinet cable splice place is provided, and the equipment that prevents hinders for some reason or the power load increase causes the too high thermometric insulating plug that then causes security incident of working temperature.
For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of thermometric insulating plug, comprise the insulator that is coated with heat-conducting connecting, and the wireless temperature measuring device that arranges in the described insulator contacts with heat-conducting connecting.
And described wireless temperature measuring device is SAW Temperature Sensors.
And described wireless temperature measuring device comprises process chip, and process chip connects with radio-frequency (RF) transmitter and temperature probe.
And described process chip is the microcontroller of 8051 classes, and described radio-frequency (RF) transmitter is that CC2410 etc. has the chip-shaped of wireless data transmittability.
And described wireless temperature measuring device comprises that less radio-frequency sends chip, and this less radio-frequency sends chip and connects with temperature probe.
And it is the radio frequency chip that CC2530 or nRF24LE1 etc. have microcontroller that described less radio-frequency sends chip.
And described insulator is rubber insulator.
The utility model can directly be measured electric complete cabinet joint temperature, and the temperature information that can wireless transmission detects; The high pressure isolation, safe and reliable; Install simple, easy to maintenance.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The present embodiment provides a kind of thermometric insulating plug, as shown in Figure 1, comprises the insulator 2 that is coated with heat-conducting connecting 1, and wherein, the wireless temperature measuring device 3 of described insulator 2 interior settings contacts with heat-conducting connecting 1.Heat-conducting connecting 1 can adopt metal material or other to have the material of thermal conductivity, and be used for and be connected the screw rod connection of complete cabinet, be the intrinsic device of insulating plug.Wireless temperature measuring device 3 contacts with heat-conducting connecting 1, is convenient to the conduction of heat.Wireless temperature measuring device 3 obtains temperature data, and then by communication, real-time sends, the extraneous temperature that just can obtain junction this moment.
Above-mentioned wireless temperature measuring device 3 can be SAW Temperature Sensors.Surface acoustic wave (claims again SAW, be Surface Acoustic Wave) be a kind of elastic wave of propagating along body surface, be the sound wave that a kind of concentration of energy that English physicist Rayleigh (Rayleigh) is found in the process of the 80's of 19th century Study of Seismic ripple is once in a while propagated in ground surface.Up to now, many SAW (Surface Acoustic Wave) device have been succeeded in developing, such as surface wave band pass filter, lag line, matched filter, temperature sensor, oscillator and surface acoustic wave convolver etc.: because the advantages such as that SAW (Surface Acoustic Wave) device has is small-sized, reliability is high, high conformity, multi-functional and flexible design, so it or is widely used in radar, communication, air traffic control, electronic warfare f microwave relay, sonar and TV.And SAW Temperature Sensors is used for the switch cabinet of converting station thermometric of power industry, is the temperature element that is directly installed on the testee surface, and it is responsible for receiving and inquires after radiofrequency signal, and returns radiofrequency signal with temperature information to reading in device.
Above-mentioned wireless temperature measuring device 3 also can be comprised of process chip, radio-frequency (RF) transmitter and temperature probe etc., and process chip connects with radio-frequency (RF) transmitter and temperature probe, can finish monitoring temperature and temperature information is sent out by communication.The process chip of this moment can be the microcontroller of 8051 classes, and radio-frequency (RF) transmitter can be that CC2410 etc. has the chip-shaped of wireless data transmittability.
Above-mentioned wireless temperature measuring device 3 can also send chip and temperature probe etc. by less radio-frequency and form, and this less radio-frequency sends chip and connects with temperature probe.It can be the radio frequency chip that CC2530 or nRF24LE1 etc. have microcontroller that the less radio-frequency of this moment sends chip.
Above-mentioned insulator can be rubber insulator.
During use, only need replace the original simple insulating plug of electric complete cabinet erection joint, as shown in Figure 2, the thermometric insulating plug 4 that installing the utility model provides gets final product.After jiont treatment is complete, near the joint, receiving antenna is installed, is received temperature data.The wireless temperature measuring device 3 that increases in the insulating plug, directly contact with the joint of electric complete cabinet, constantly accurately monitor the working temperature of joint, then by the emitter that carries temperature signal is sent in the outside receiving trap, receiving trap is analyzed monitoring to temperature, and provide the work such as warning, record.Simultaneously, this thermometric insulating plug guarantees original insulation distance, and dielectric strength does not change.
