The technical scheme that its technical matters that solves the utility model adopts is: based on the insulation contact box, inject induction power supply, with thermal detector, photoelectric transformer, infrared transmitting tube, the structure of a kind of novel high voltage temperature on-line monitoring optronic switching contact box that infrared receiving tube and output wiring terminal and lid are formed, it is characterized in that: a contact box main body is arranged, main body upper end one side offers through hole, the interior inside of going up the side through hole inboard of main body is injected with the induction power supply in the insulator, and induction power supply is connected so that its working power to be provided with photoelectric transformer by lead-in wire; The main body inner chamber is fixedly being imbedded thermal detector on the inserts on the inwall of position of center line, and to detect the static contact temperature, its lead-in wire is connected with the input temp signal with photoelectric transformer; Main body is provided with a hole that the left and right sides is penetrating at the corresponding opposite side of upper end through hole, and the left end in hole is equipped with the infrared transmitting tube that is connected with photoelectric transformer, and the right-hand member in hole is equipped with infrared receiving tube; The top of main body is provided with a lid on the position of photoelectric transformer; The lower end of main body is provided with output wiring terminal at the right-hand member place that is connected with infrared receiving tube.Temperature signal is transmitted to infrared receiving tube by infrared transmitting tube with it; Infrared receiving tube changes light signal into electric signal again, is connected with the control module of outside by output wiring terminal; Finally finish on-line temperature monitoring and realize temperature protection.Openable lid is that the installation of being convenient to them connects and debugging.
Be the slotted hole of diameter between described infrared transmitting tube and the infrared receiving tube, and they are enclosed in wherein greater than φ 5mm; Described contact box insulating material main body is materials such as epoxy resin, SMC unsaturated polyester and comprises fixedly inserts; Described induction power supply and lead-in wire thereof inject when the cast contact box together, and its lead-in wire is arranged arbitrarily along the edge, but should be convenient to be connected with photoelectric transformer; Described thermal detector is imbedded after being, lead-in wire is connected with photoelectric transformer; Described photoelectric transformer is to be screwed on contact box; Described infrared transmitting tube links together with photoelectric transformer; Described infrared receiving tube be contained on the contact box after output wiring terminal is connected.
The utility model is applicable to the different contact boxs of large, medium and small complete series rated current.
The beneficial effects of the utility model are: because the utility model adopts high voltage temperature on-line monitoring optronic switching contact box, thermal detector directly contacts the measured point and accurately detects its temperature, realize High-Voltage Insulation by contact box, transmit temperature signal, isolate high and low voltage by infrared light.Realize accurate, reliable high-tension on-line temperature monitoring.Owing to keep the basic structure of original contact box.So keep the function of former contact box, former installation dimension is constant simultaneously, and the scrap build in being more convenient for using is changed or the like.In addition, infrared transmitting tube of the present invention and infrared receiving tube are that sealing is fixing, not influenced by the external environment filth.Therefore, the utility model can reach the purpose of the real time temperature on-line monitoring of the dynamic and static contact splicing position of high voltage in the contact box.
