Description
Technical field
The present invention relates to the temperature on-line monitoring device of high-voltage power equipment, a kind of specifically high pressure temperature on-line monitoring photoelectricity inversion thimble structure.
Background technology
The electric contact state of power equipment conduction junction, splicing position is bad to be the major reason that causes that this place's temperature is too high, even also can surpass the highest temperature perhaps of filling under normal current.The position that switchgear often breaks down is contact and turnover line end cable junction.These equipment mostly are enclosed construction, can not open the door or the cover plate that block infrared radiation during operation and carry out infrared detection; Some outdoor equipment inconvenience detects, and detected temperatures is inaccurate again can not on-line monitoring.
For present withdraw-type switchgear on-line temperature monitoring the contactless infrared sensor of employing is arranged, because it is influenced by environment, humidity, atmospheric pressure, infrared radiation is just blocked and can't accurately be detected, and using has very big limitation.And the temperature sensor of contact directly with the measurement point contact position at high voltage end, the control module that detects processing is in low-pressure system.In order to prevent that high voltage from scurrying into low-voltage system, have at present the optical fiber of employing directly in air, connect, by infrared light simply in air transmission signals, with three kinds of mode isolated high voltage such as wireless electromagnetic emission with transmit temperature signal.Because they are subjected to that the environment dirt moves, electro-conductive dust, humidity or the interference of electromagnetic field etc. influence, and have factors such as dangerous and unreliable; Simultaneously, the basic structure that their installation all can switching devices plays certain destruction.The application of high voltage temperature on-line monitoring optronic switching contact box can solve the problem of above-mentioned existence well.But it is mounted on the cabinet of switchgear, is to be connected with main bus-bar, installs very convenient when switchgear is made.But just must having a power failure and could install by main bus-bar for the scrap build in running status, can influence other loop power supplies, is not allow long-time the power failure for important loop especially.
Summary of the invention
In order to overcome the deficiency that existing power equipment on-line temperature monitoring exists, the present invention proposes the new structure of a kind of high voltage temperature at the monitoring of photo-electric conversion embedded collar in the applicant's invention " high voltage temperature is in the structure of monitoring of photo-electric conversion embedded insulator " on the basis of the patent No.: ZL03257238.7.
The technical solution adopted for the present invention to solve the technical problems is: based on the insulation collar (sleeve pipe), inject induction power supply, a kind of high pressure temperature on-line monitoring photoelectricity inversion thimble structure with compositions such as thermal detector, photoelectric transformer, infrared transmitting tube, infrared receiving tube and signal output wiring terminals, it is characterized in that: a collar main body is arranged, collar body front end is provided with a circular ring, and inner embedding of the collar has induction power supply; Collar main body upper end is provided with photoelectric transformer; The other end that photoelectric transformer is connected with lead-in wire is connected with induction power supply; Be connected with thermal detector on the photoelectric transformer, the sensing temperature signal is touched at thermal detector and external detection temperature position; Photoelectric transformer is inner to be connected with infrared transmitting tube, and infrared transmitting tube is to there being a penetrating hole, and the other end in hole is provided with infrared receiving tube, and the infrared receiving tube other end is connected with the signal output wiring terminal; Connection terminal is connected with the external control unit by line.
Described infrared transmitting tube can be connected with optical fiber, and optical fiber passes the hole and is connected with infrared receiving tube on the outside control module.
The optical fiber that described infrared transmitting tube connects also can not adopt penetrating perforation and directly be embedded in the main body, is connected to the infrared receiving tube on the outside control module.
The described collar can be inserted in sleeve pipe at its head.
The described collar or quill are to having perpendicular with the infrared light transmission direction and paralleling two kinds of patterns.
The present invention can be installed on the handcart of withdraw-type switchgear, is convenient to use in the fortune scrap build.It can also be installed on the power equipment such as switch, transformer of overhead transmission line.It is a modular structure, and is safe in utilization, reliable, convenient.
The invention has the beneficial effects as follows: the utility model temperature-sensitive thermal detector is the tested position of contact directly, measures accurately.The power supply of employing induction power supply need not be changed battery.Adopt the modularization enclosed construction, be not subjected to external environment condition, light, electric and magnetic interference, do not influence power equipment basic structure, safe in utilization, reliable, convenient.The present invention can be installed on the handcart of withdraw-type switchgear easily, is convenient to reduce between the stopping time and the power failure scope in fortune switchgear technological transformation usefulness.The present invention can also use on power equipments such as pole line switch, transformer.Realize high-voltage power device temperature on-line monitoring.To reducing the power equipment accident, improve power supply reliability, be convenient to realize equipment state overhauling and distribution network automated, have good social benefit.
