Abstract
The utility model discloses an on-line temperature detecting and sending device for contacts of a voltage switch cabinet. Temperature sensors are arranged at a plurality of conductive bar contacts of the voltage switch cabinet and detect real-time temperature of conductive contacts in a on-line form, all the temperature sensors are connected with a microprocessor chip, data of the temperature sensors of the conductive bar contacts are grouped by the microprocessor chip and then are sent to an infrared emitter to be emitted, an infrared receiver arranged at a remote terminal is connected with a display and an alarm driving circuit respectively to implement data display or alarming, and the device adopts an on-line induction power source. The on-line temperature detecting and sending device for contacts of a voltage switch cabinet has the advantages that as the device adopts a battery-free mode, induction voltage of detected conductor is converted into low-power-consumption working power for a wireless emitter, and the device can not be affected by space of assembled equipment; and the device adopting the infrared isolation technology has the advantages of thorough isolation, strong interference resistance capacity, reliable operation, convenient installation and the like, and can resolve problems about temperature monitoring in high voltage state.

Technical field
The utility model relates to a kind of dispensing device, the online temperature detection dispensing device in particularly a kind of voltage switch cabinet contact.
Background technology
Usually " electric control appliance " all needs electrical parameter is measured, and tackles components and parts and carry out the requirement of effective input, and its conventional transportation method generally is to adopt optical cable to transmit.When the secondary detection components and parts are installed, all can be subjected to the restriction and the constraint (as being used in the equipment of the above middle and high pressure of nominal operation 3KV) of equipment rated operational voltage and relevant insulation index.When installing the secondary detection components and parts additional, exist and do not satisfy the conditional request that matches with whole set equipment insulation index, more can't accomplish in a big way, to deacclimatize the rated operational voltage classification standard category that is changing, directly influence the supporting use of normal selection of product, make product loss of life power.
The utility model content
Technical problem to be solved in the utility model is will provide a kind of induced voltage with tested electric conductor to convert to can provide the voltage switch of wireless launcher working power cabinet contact online temperature detection dispensing device.
In order to solve above technical matters, the utility model provides a kind of voltage switch cabinet contact online temperature detection dispensing device, several places, busbar contact are provided with temperature sensor at the voltage switch cabinet, the real time temperature of online detection conductive contact, all temperature sensors are connected with microprocessor chip, after little process chip is organized into groups processing to a plurality of busbar contact temperature sensing datas, deliver to the infrared transmitter emission, be provided with infrared receiver at remote terminal, infrared receiver is connected with the warning driving circuit with display respectively, implementation data shows or reports to the police that used power supply is online induction power supply.
Described online induction power supply is to be provided with the induced voltage sensor near the busbar contact, and the alternating voltage of induced voltage sensor sensing is DC voltage behind rectifying and wave-filtering.
Superior effect of the present utility model is: adopt no battery mode, the induced voltage that is about to tested electric conductor converts to can provide wireless launcher low-power consumption working power, is not subjected to the influence in installed equipment space; Use technology such as infrared isolation, have isolate thoroughly, antijamming capability is strong, reliable operation, characteristics such as easy for installation, can solve the temperature monitoring problem under the high-voltage state, is present comparatively ideal switch cubicle thermometric solution.And can find secret in advance after using this device, electric fault is nipped in the bud.For the power transmission and distribution switching control device can safe and reliable operation provide the otherwise effective technique assurance.
