Abstract
The utility model discloses an optic-photo transfer insulator structure for supervising high voltage temperature online. The utility model takes insulating material as a main body, an input connecting terminal is connected with a temperature electronic-to-optical transducer in the main body and an infrared transmitting valve is arranged on the transducer, and an infrared collecting tube is connected with an output connecting terminal at the other end in the main body, thus forming the structure of the utility model. The utility model not only has good electric insulation performance of the high voltage insulator, but also can introduce and change high voltage and temperature signal directly measured by a thermodetector through the transducer into optical signal through the input connecting terminal, then transform thereof into relevant low voltage electric quantity signal through the infrared transmitting valve and the infrared collecting tube, further transmit to a control unit through the output connecting terminal, thereby online supervision and protection functions for temperature are completed. The actual and accurate temperature of every part of high voltage electric equipment can be measured by the utility model, when in running.
Description
Technical field
The utility model relates to the on-line temperature monitoring of electrical equipment in 10KV and the above high voltage electrical power trans mission/distribution system, a kind of specifically structure that temperature value on the high voltage is transformed into the high-voltage on-line temperature monitoring of photo-electric conversion embedded insulator of corresponding low-voltage charge value by infrared ray photoelectricity.
Background technology
Detect at present the temperature that cable in 10KV and the above electrical equipment, bus, switch, electrical equipment, transformer etc. are in operation, the general infrared detector that adopts, this is a kind of measurement that does not directly contact tested position, and it is subjected to difference, angle, distance and the metal at tested position still is the not accuracys of equal factor affecting dut temperature value of nonmetallic materials.Simultaneously when unit under test by the sealing of metal or insulator, when wrapping up or blocking, promptly can't measure temperature really and accurately.In addition, along with measured point or infrared light emission pipe are subjected to the influence of environment filth in various degree, make and measure temperature value and have in various degree on the low side.Therefore there is the problem of measuring confidence level in the infrared detector that uses at present.
Show that from the interrelated data retrieval that comprises Chinese patent the relevant report of the structure of high-voltage on-line temperature monitoring of photo-electric conversion embedded insulator is not arranged at present as yet.
The utility model content
Do not have the accurately equipment of monitoring of high voltage temperature in the prior art in order to overcome, the utility model provides a kind of structure of novel high-voltage on-line temperature monitoring of photo-electric conversion embedded insulator.
The technical scheme that its technical matters that solves the utility model adopts is: based on insulating material, seal and become to have the temperature electrical to optical converter, the structure of a kind of novel high-voltage on-line temperature monitoring of photo-electric conversion embedded insulator that infrared emission tube, infrared receiver tube etc. are formed, it is characterized in that: based on insulating material, connect the temperature electrical to optical converter by the input wires terminal in the main body, infrared emission tube is arranged on the converter, the other end in the main body has infrared receiver tube to be connected with output wiring terminal, and they have formed structure of the present utility model.
Be with insulating sleeve between described infrared emission tube and the infrared receiver tube; Described insulating material main body is epoxy resin, silicon rubber and ceramic material; Described infrared emission tube and infrared receiver tube can be 1 group to 8 groups; Described input wires terminal and the temperature electrical to optical converter that is connected, comprise infrared emission tube and infrared receiver tube and between insulating sleeve and output wiring terminal all become high-tension insulator through cast or assembling rear enclosed by insulating material.As long as the utility model is linked into high-tension input end, the other end is connected just can be implemented under the high-tension situation with the output terminal of low tension has again monitored the electrical equipment conductor temperature during use.
The beneficial effects of the utility model are: the conductor temperature that adopts the direct method that contacts tested position of thermal detector to detect high voltage electric apparatus can solve infrared detector and have the problems such as inaccurate that detect, but the High-Voltage Insulation difficult problem between necessary solution thermal detector and the control module.The utility model solves the Insulation Problems between thermal detector and the control module, the utility model not only has the good electrical insulating property of High-Voltage Insulation, and by the high voltage temperature signal of converter with the direct contact measurement of thermal detector, import into by the input wires terminal and to convert light signal to, become the low-voltage electric quantity signal by infrared, receiving tube propagation and transformation again, send control module to by output wiring terminal.Finishing temperature online detects and defencive function.Because infrared emission tube and receiving tube are insulated sleeve pipe, the insulating material sealing is fixing, are not subjected to the external environment filth.Be set a distance between infrared emission tube and the receiving tube, temperature signal is again direct sensing contact, so overcome above-mentioned uncertain factor and be closed, wrapping up or the situation of blocking influences the defective of measured temperature, utilized the utility model can realize detecting the operating true and accurate temperature in each tested position of high voltage electric equipment.So the utility model can reach the purpose of drafting.
