Description
Affiliated field
The utility model relates to device for detecting temperature, particularly power equipment junction surface on-line temperature monitoring instrument.
Background technology
At present, the high voltage electric power equip ment transformer, current transformer, voltage transformer (VT), disconnector, the coupling part of isolating switch etc., domestic, all adopt two plates to connect abroad with bolt, this connection is because the line of electric force swing, the power equipment vibration can cause bolt looseness, and bolt looseness causes the connecting portion contact resistance to increase, and powerful electric current can produce high heat by web joint, this high heat can cause a serious accident, as catch fire, even blast, address this problem main employing thermal imaging system both at home and abroad according to taking the photograph, to transformer station, all connecting portions of power house are all according to taking the photograph, find high hot plate, have a power failure and handle that this way is to make regular check on, cycle is very bad definite, if the bolt that has is to take place after checking; Or adopt the cured web joint surface that drops in of solid, and the personnel of making regular check on can find which cured is disappeared, promptly this tie point will overhaul, and in a word, still can cause the accident, and influences the safety of power equipment, demands urgently improving.
Summary of the invention
The purpose of this utility model provides a kind of by the temperature sensor step switch, transmits and receives a kind of power equipment junction surface on-line temperature monitoring instrument of high-frequency signal by Computer Processing and demonstration.
Power equipment junction surface on-line temperature monitoring instrument comprises temperature sensing utensil 1, HF transmitter 2 and computing machine 3, it is characterized in that temperature sensor 1 places web joint bolt place, circuit inserts on the switch 5, and switch 5 connects HF transmitter 2, and the high-frequency receiver 4 of received signal connects computing machine 3.Principle of work: sensor action when 70 ℃ of temperature of splicing ear heating, the switch closure HF transmitter is connected, and high-frequency switching signal sends, and high-frequency receiver receives signal, passes to computing machine, the computing machine display process.
The utility model is a temperature sensor technology, the combination of high frequency transmit-receive technology and computer technology, its modern design, simple in structure, make easily, easy to use, problems such as manpower and operation cost height have been solved, can realize real time on-line monitoring, pinpoint the problems at any time, can avoid the generation of major accident, this combination has a kind of beyond thought effect, having realized high voltage electric power equip ment junction surface on-line temperature monitoring, is desirable power equipment junction surface device for detecting temperature, is easy to penetration and promotion.
Description of drawings
The utility model accompanying drawing 1 is a structural representation, and Fig. 2 is the web joint structural representation, and wherein temperature sensor 1, HF transmitter 2, computing machine 3, high-frequency receiver 4, switch 5.
Embodiment
A type power equipment junction surface on-line temperature monitoring instrument is applicable to 60 kilovolts of power equipments, and temperature sensor 1 is temperature detect switch (TDS) KSB302, and HF transmitter 2 and high-frequency receiver 4 are P12262, and computing machine is a programmable single chip computer.
Temperature sensor 1 is temperature detect switch (TDS) KSB302, and when measured point terminal temperature is below 70 ℃ the time, the normally closed transmission signals of temperature detect switch (TDS) is a working signal, and when measured point terminal temperature during greater than 70 ℃, temperature detect switch (TDS) is opened, and transmission signals is a trouble-signal.
HF transmitter 2, when measured point terminal temperature is below 70 ℃ the time, the emission working signal is when temperature during greater than 70 ℃, emission accident alarming signal, transmit frequency band 415M, 433M or 418M, and adopt the coding emission, and emissive power is below 500mW, and the distance that is transmitted into acceptance point is less than 100m.
High-frequency receiver 4, form by two parts, a part detects the unified receiver of transmitting set for cluster, reception is 50 from each every group, can receive 200 simultaneously, the switching value signal that has coding of transmitter enters intelligent controller by amplifier, to the coded signal that the receives recognition of sorting; Another part is a terminal, and detected working signal ordering is broadcasted, and when receiving trouble-signal, shows accident condition, and drives the emergency alarm bell warning, reminds the operator on duty to note.
