Abstract
The utility model discloses a leakage protector test instrument, which comprises a shell, wherein the shell is provided with a switch and an indication switch, the shell is provided with a first test end and a second test end, and the first test end, the switch, the indication lamp and the second test end are sequentially connected with each other through a conducting wire. The leakage protector test instrument has the advantages that the test instrument can test whether the leakage protector has the leakage protection function or not, and the detection result is correct and reliable; the structure is simple; the production cost is low; and the operation is easy.
Description
Technical field
The utility model relates to earth leakage protective device pick-up unit field, specifically is a kind of tester for leakage protector.
Background technology
Earth leakage protective device is the electric elements that we often use in productive life, and installing and using earth leakage protective device also is the important salvo of safety utilization of electric power.When judging the creepage protection function of earth leakage protective device; generally be by the test button on the lower panel under user mode; if mechanism's tripping would illustrate qualified; but the quality of earth leakage protective device on the market is very different now; some producers have produced some fake and forged leak source protectors in order to reduce cost; this class protector is pressed test button at the trial and also can be tripped, but occurs can't tripping when real damage in insulation personnel get an electric shock, and user's personal safety is caused very big threat.Qualified earth leakage protective device is outer side joint one resistance at the zero sequence current mutual inductor of protector; one of resistance terminates on the protector input side live wire; the other end is connected on the zero line of protector outgoing side; loop indirect one button test button; when pressing the button; will mutual inductance go out electric current in the zero sequence current mutual inductor in the protector; behind amplifier element, go to carry out tripping operation; and the earth leakage protective device of personation reduces manufacturing cost; removed most important components and parts--zero sequence current mutual inductor in the earth leakage protective device; when pressing test button, just start an inner electromagnet and gone to back down mechanism's tripping operation, this class earth leakage protective device is without any defencive function.It is too complicated that the apparatus structure of earth leakage protective device can be detected in present market, and complex operation is difficult for using the cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of tester for leakage protector, and it can solve the deficiency that exists in the known technology, and is simple for structure, can test earth leakage protective device fast and whether have defencive function, and testing result accurately and reliably.
The utility model for achieving the above object; be achieved through the following technical solutions: a kind of tester for leakage protector; comprise housing; switch and pilot lamp are installed on the housing; first test lead and second test lead are installed on the housing, and first test lead, switch, pilot lamp and second test lead are connected successively by lead.
Advantage of the present utility model is: can test earth leakage protective device and whether have creepage protection function, testing result accurately and reliably; Simple for structure; Low cost of manufacture; Easy operating etc.
Description of drawings
Accompanying drawing 1 is a main TV structure synoptic diagram of the present utility model.
Embodiment
The utility model is described in further detail for the contrast accompanying drawing:
Agent structure of the present utility model has: comprise housing 2, switch 1 and pilot lamp 8 are installed on the housing 2, first test lead 3 and second test lead, 7, the first test leads 3, switch 1, pilot lamp 8 are installed on the housing 2 are connected successively by lead with second test lead 7.
When the utility model uses, earth leakage protective device 6 is set in gate-dividing state, first test lead 3 connects arbitrary live wire 5 of earth leakage protective device 6 input sides by lead, second test lead 7 is connected with the zero line 4 that connects earth leakage protective device 6 outgoing sides by lead, earth leakage protective device 6 then closes, close a switch 1 at last, if earth leakage protective device 6 tripping operation at once illustrates that then earth leakage protective device 6 is qualified; If earth leakage protective device 6 does not trip, and pilot lamp 8 is bright, illustrates that then earth leakage protective device is defective, and test result is accurate, and is easy to use.
