Description
Technical field
The utility model patent relates to a kind of micropower wireless temperature pick-up unit, relate in particular to a kind of online detection and early warning that is used for the high-tension switch gear contact temperature, accident potential is eliminated in bud, improved the security and the reliability of switchgear operation, belong to the energy monitoring apparatus field.
Background technology
In electric system, 10kV～35kV high-tension switch cabinet is not often just waiting manufacturing owing to contact loose contact, grafting off-centre or is using, and causes contact temperature to raise unusually.If can not in time find, tend to cause contact oxidation acceleration and insulation ag(e)ing to puncture, cause internal arc, cause serious electric power accident and enormous economic loss.According to State Grid security incident circular statistics, the etesian electric power accident of China 40% be since main conductive circuit overheated due to, had a strong impact on the safe and stable operation of electric system.
High-tension switch cabinet is a high voltage alive equipment, and the space sealing is narrow and small, finds so heat generating spot is difficult for detecting and is difficult to.Detection method relatively more commonly used at present has variable color sheet, some Wen Yi, infrared thermography etc., these methods need special operator on duty's regular visit, can not teletransmission, can't detect by real-time online, more can not in time alarm, can not apply as a kind of proper prophylactic methods to the temperature anomaly situation.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provide a kind of and detect each contact tie point state of temperature of high-tension switch gear in real time in the micro power radio communication mode, and the micropower wireless temperature pick-up unit that the temperature anomaly situation is carried out online warning.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of micropower wireless temperature pick-up unit, comprise the hollow circuit cylinder sleeve, an end is provided with ring-type CT power supply coil in the described hollow circuit cylinder sleeve, the other end is provided with temperature data acquisition treatment circuit plate, radio transmitter plate and wireless receiving circuit plate, described temperature data acquisition treatment circuit plate one end links to each other with ring-type CT power supply coil, the described temperature data acquisition treatment circuit plate other end links to each other with the wireless receiving circuit plate with the radio transmitter plate, the inwall place of described hollow circuit cylinder sleeve is provided with breach, be provided with temperature sensor in the described breach, described temperature sensor links to each other with temperature data acquisition treatment circuit plate by reed, and the epoxy resin layer encapsulation is adopted at the two ends of described hollow circuit cylinder sleeve.
As preferably, described temperature data acquisition treatment circuit plate, radio transmitter plate and wireless receiving circuit plate are triangular shape and distribute on same circumference.
Principle of work: CT power supply coil from the power taking of primary current loop, provides working power for temperature data acquisition treatment circuit plate, radio transmitter plate and wireless receiving circuit plate by electromagnetic induction.Temperature sensor is attached to the isolating switch contact arm front end of close heat generating spot by reed, the contact temperature data that collect are input in the temperature data acquisition treatment circuit plate handle by single-chip microcomputer, data after the processing send the radio transmitter plate to by data line, finally gather communication terminal by the scene that sends on the switch cubicle control panel after the modulation of radio transmitter plate.The temperature data that communication terminal sends by each micropower wireless temperature pick-up unit in the wireless mode receiving key cabinet is gathered at this scene, after data demodulates, directly gather demonstration on the spot, and pass through the RS485 serial line interface the monitoring backstage of data transmission to transformer station.The monitoring backstage shows the temperature data of the different points for measuring temperature of each switchgear in the transformer station in real time, and to the timely alarm indication of temperature anomaly situation, realizes online detection and early warning to temperature rise point in the high-tension switch cabinet.
The utility model compared with prior art, its beneficial effect is:
1) the telescopic mounting structure of employing is convenient for installation and maintenance, need not any external cabling, directly is enclosed within on the isolating switch contact arm to get final product.Fully sensor and each circuit part are concealed between contact arm and sleeve, can not reduced the original insulating property of switchgear; Bush material has the performance of withstand high temperatures simultaneously, guarantees reliable and stable work under hot environment.
2) wireless communication technology of employing micropower, emissive power can break through the metallic shield in the switch cubicle less than 10mW, realizes high-low pressure isolation and data transmission effectively, and can not produce interference to other wireless telecommunications.
3) CT power supply coil, can be powered from the power taking of primary current loop continuously by electromagnetic induction, has avoided the short and fried danger of chance high temperature explosive of battery service life fully.
