Abstract
The utility model discloses a high-voltage test safety protection device of a transformer substation. The high-voltage test safety protection device consists of a telescopic supporting rod, an infrared probe, a relay and an alternating current contactor connected with a main test power line, wherein the infrared probe is arranged on the telescopic supporting rod; and the infrared probe, the relay and the alternating current contactor are sequentially connected with one another through conductive lines. The protection device can effectively prevent people from entering a high-voltage test area; once someone enters the high-voltage test area by mistake, a test system is immediately powered off and stopped and instantly sounds a voice alarm; the test failure judgment and handling process is simplified, so that the safety of a high-voltage test can be guaranteed reliably; by using the device, a large quantity of labors can be reduced; and the device has the advantages of reliable performance, simple structure, convenience in mounting and use and the like.
Description
Technical field
The utility model belongs to power transformation system job safety protection technique field, particularly a kind of transformer station high-potting safety device.
Background technology
The high-voltage transforming of electric system stands in after each installation and the cycle maintenance, all must carry out prerun, and prerun is qualified, and each one all could drop into commencement of commercial operation after the operational-condition compliance.In the process of carrying out prerun, must strictness forbid that personnel get in the high-potting zone, otherwise serious pernicious human casualty accident will take place.At present; Security protection to high pressure prerun mostly is the mode that adopts the personnel guard of gathering; This method not only need take great amount of manpower, and poor reliability, and the guard unless you give your whole attention to it; Promptly the someone is strayed into the high-potting district easily, so the serious accident in the electric system high-potting happens occasionally.
The utility model content
The purpose of the utility model is to provide a kind of can prevent effectively that personnel from getting into the high-potting district, reduces work and takies, and ensures transformer station's high-potting safety device of testing operation safety.
The technical scheme that purpose adopted that realizes the utility model is: a kind of transformer station high-potting safety device; Form by telescopic strut, infrared probe, relay and the A.C. contactor that is connected with test general supply line; Infrared probe is installed on the telescopic strut, and infrared probe, relay and A.C. contactor are connected through the conducting wire successively.
Said infrared probe is connected with phonetic alarm through signal transmssion line.
Transformer station's high-potting safety device of the utility model; Can prevent effectively that personnel from getting into the high-potting district; And in case when having the people to be strayed into the high-potting district, pilot system will be cut off the power supply immediately and stopped, and the instantaneous audio alert that sends; Short form test fault judgement and disposal guarantee the safety of high-potting thus reliably.And, advantage such as the use of this device can reduce a large amount of work and take, and has dependable performance, and is simple in structure, easy to install.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1, transformer station's high-potting safety device of the utility model is made up of telescopic strut 1, infrared probe 3, relay 6 and the A.C. contactor 5 that is connected with test general supply line 4, and infrared probe 3 is installed in the top of telescopic strut 1.Said infrared probe 3, relay 6 are connected through the conducting wire with A.C. contactor 5 successively.Said infrared probe 3 is connected with phonetic alarm 2 through signal transmssion line.When this device uses telescopic strut 1 is put in position; And the height of adjustment telescopic strut 1, make infrared probe 3 search coverages cover whole high-potting district, do not stay the dead angle; In case there are personnel to be strayed into the test site; Infrared probe 3 sends signal to relay 6 and A.C. contactor 5 through signal transmssion line successively, and A.C. contactor 5 cuts off the test general supply at snap action, prevents the generation of serious accident effectively; And send warning, short form test fault judgement and disposal through phonetic alarm 2.
