The main structural point is that the check device comprises a control circuit, a smoke generator and a transmitting gas-guide tube, and the control circuit comprises a signal input module, a signal processing module, a controlled switch module and an oil pump which are in electric connection sequentially and a rectification module supplying power for the modules. The output end of the oil pump is connected with the smoke generator which is an inner heating container, and the transmitting gas-guide tube is communicated with the inner heating container and a transformer substation outdoor terminal box. The sealing check device adopts the tailor-made control circuit to start up a small size oil pump, extracts purpose made oil to heat so as to form pressured smoke which releases to the outdoor terminal box through the gas-guide tube, and users can judge defect points of the terminal box according to escaped smoke. The sealing check device is simple in integral structure, convenient and fast in operation process, accurate and effective, and breaks through limitation that the existing sealing check device can only work at night.
Description
Technical field
The utility model relates to a kind of testing fixture of water-tight equipment, particularly a kind of transformer station Outdoor Terminal Case seal detecting apparatus.
Background technology
Transformer station's Outdoor Terminal Case makes the terminal box poor sealing owing to expose to the sun and rain, design unreasonable or with reasons such as material do not pass a test, after certain tenure of use, all can cause aging, the distortion of sealing strip throughout the year; Thereby bring a series of problems: at first be wet environments such as rain, snow, greasy weather when producing rainwater infiltrate, cause the short circuit of terminal box internal circuit, lost territory easily, influenced the correct operation of protection, and then the stability of the area power grid of influence.In addition, the transformer station insect that is located in mountain area, field during spring and summer is many especially, and when the Outdoor Terminal Case poor sealing, insect will climb into box house, not only makes terminal dirty, need often sweep, and increases workload; Secondary connection that the more important thing is the terminal box equipment is adjacent each other; The distance of two terminals between 1～5mm, is liked the random insect that climbs everywhere usually, maybe will cause AC and DC loop insulation resistance to reduce; Or ground connection or short circuit; Or make protective relaying maloperation or tripping etc., and operating secondary connection in the terminal box has been constituted serious threat, exist serious accident potential.Can simple and efficient inspection go out the seal degree of Outdoor Terminal Case, thereby take proper prophylactic methods, the important topic that has become each power department to face.
Before, the method for transformer station's Outdoor Terminal Case leakage check mainly had been to lean on the method for the light leak inspection in evening, and whether this method is to have the light leakage phenomena of generation to judge seal degree at night with the torch irradiation.This method can not effectively check light transparent member (like organic glass) is arranged, simultaneously since present a lot of casings for waterproof, take have groove and an anti-embedding structure, light leak inspection just can not accurately judge whether effective sealing like this.
The utility model content
The purpose of the utility model is that the weak point according to prior art provides a kind of simple and efficient, transformer station's Outdoor Terminal Case seal detecting apparatus accurately and effectively.
The purpose of the utility model realizes through following approach:
Transformer station's Outdoor Terminal Case seal detecting apparatus; Its structural feature is; Include control circuit, aerosol producer and transmit wireway; Control circuit includes signal input module, signal processing module, gate-controlled switch module and the oil pump that is electrically connected in regular turn, and is the rectification module of above-mentioned module for power supply; The output terminal of oil pump is connected with aerosol producer, and aerosol producer is a kind of interior heating container, transmits wireway and is communicated with interior heating container and transformer station's Outdoor Terminal Case.
During use, the signal input module input instruction signal is after the signal processing module processing; Trigger the gate-controlled switch module, thereby start oil pump, oil pump is extracted tailor-made oil out; And deliver in the aerosol producer, be formed with the smoke-like mist of oil of certain pressure through heat treated, and pass through to transmit in the wireway entering terminal box; Reveal when the seals at generation smog of certain Outdoor Terminal Case, just can find the leak point to carry out encapsulation process fast and accurately.Because in the terminal box is electric secondary wiring circuit, so can not adopt the smog of general water attribute to survey, the utility model adopts the smog of oily attribute to survey and has avoided the problems referred to above.Simultaneously, smoke detection can be carried out sealing detection in more environment, and need not stick to night, thereby better working environment just can be arranged when patrolling and examining terminal box, so the utility model is simple in structure, and is simple and efficient to handle, effectively simple.
The utility model can further be specially:
The signal input module of control circuit kind is a kind of remote input units, includes telepilot and FM reception module.
Telepilot is provided with the frequency consistent with the FM reception module, input instruction on telepilot then, and send to the FM reception module, by FM reception module reception signal, send the rear processing module again to.
Signal processing module includes signal amplifying apparatus and detection apparatus for shaping.
Signal processing module can adopt a kind of demodulation integrated package to realize, it has signal and amplifies and the detection shaping feature.
The gate-controlled switch module includes photoelectrical coupler, photosensitive trigger tube and the controllable silicon that is electrically connected in regular turn.
After receiving the trigger pip of signal processing module, lumination of light emitting diode in the photoelectrical coupler; Further make controllable silicon T1 triggering and conducting behind the photosensitive trigger tube of conducting, start the oil pump running that connects on its loop.
In sum, the utility model provides the seal detecting apparatus of a kind of transformer station Outdoor Terminal Case, adopts special control circuit to start small-sized oil pump; Extract tailor-made oil and heat the smog that is formed with pressure; Be discharged in the Outdoor Terminal Case through wireway, according to the poor sealing point of the smog judgement terminal box that leaks, one-piece construction is simple, operating process is simple and efficient; And accurate and effective, broken through original can only be in the restriction of night work.
Description of drawings
Shown in Figure 1 is the structural representation of the said transformer station of the utility model Outdoor Terminal Case seal detecting apparatus;
The circuit diagram of control circuit in the said seal detecting apparatus of the utility model shown in Figure 2.
Below in conjunction with embodiment the utility model is done and to be further described.
Specific embodiment
Most preferred embodiment:
With reference to accompanying drawing 1; Transformer station's Outdoor Terminal Case seal detecting apparatus; Include control circuit, aerosol producer and transmit wireway, the oil pump in the control circuit, output terminal is connected with aerosol producer; Aerosol producer is a kind of interior heating container, transmits wireway and is communicated with interior heating container and transformer station's Outdoor Terminal Case.
