Description
Technical field
The utility model relates to a kind of pick-up unit, and particularly a kind of arclight signal self-checking unit be applicable in switch cabinet arc light protection system, belongs to switching technique field.
Background technology
Along with the fast development of power industry, in, the number of applications of low-tension switch cabinet gets more and more, the middle voltage bus bar fault caused because of high-voltage board arc short-circuit is also shown in not new repeatly, not only causes economic loss, and very easily works the mischief to the personal safety of operating personnel.Think and reduce the loss that causes because of arc short-circuit and harm; insider take arc photosensor as major component; have developed a kind of arc light protecting system; it can by the arc light intensity detected; judge whether in time to carry out power-off protection, thus efficiently solve the problem such as economic loss and personnel's injury caused because of arc short-circuit.But arc photosensor is as very important electrical equipment in a protection system, and it not only will have quick measuring ability when arc light occurs, also will have the diagnostic function of self duty, effectively could ensure the reliability that arc light detects like this.So; if do not have the autodiagnosis ability of detection system in electric arc light detection system; then can when arc probe or Fiber optic delivery systems break down; warning function cannot be played quickly and effectively; and may occur because of self light path system fault produce false judgment; make system protection occur maloperation, large-scale power system equipment is caused damage.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of use safety, easy for installation, and has the arclight signal self-checking unit compared with high detection performance.
Problem described in the utility model solves by the following technical programs:
A kind of arclight signal self-checking unit, it comprises support, self-test signal source and optically focused probe; Described optically focused probe and self-test signal source are all fixed on support by fastening part; Described self-test signal source is positioned at the side of optically focused probe; The input end in described self-test signal source is connected with external power supply; The output terminal of described optically focused probe is connected with external protective device through optical fiber.
Above-mentioned arclight signal self-checking unit, described self-test signal source is dodge LED second.
Above-mentioned arclight signal self-checking unit, described fastening part comprises probe socket and joint pin; Pop one's head in optically focused and be connected in one end of described probe socket, the other end is fixed through the first nut through after support; One end and the second of described joint pin dodge LED and are connected, and the other end is fixed through the second nut through after support.
Above-mentioned arclight signal self-checking unit, sets up optical fiber fastener, and described optical fiber fastener is the loop configuration steel of opening; Described probe socket is tightened together with optical fiber by optical fiber fastener.
Above-mentioned arclight signal self-checking unit, set up insulating bolt, one end of described insulating bolt is threaded with joint pin, and the other end is connected with the second nut thread.
The utility model to dodge by optically focused probe acquires the low light signals that LED sends second; the information collected by optical fiber is again as self-test signal; be transferred to protection circuit; after this signal of protection circuit process; send alerting signal; thus judge that protection circuit work is whether normal, have effectively achieved and optically focused probe and the whether normal of protection circuit are monitored in real time, prevent from causing because its damage the generation of the erroneous judgement of arc protection circuit or the situation such as undetected.The utility model structure is simple, easy for installation, has higher adaptability, is applicable to match in any arc light protecting system.
