Abstract
The utility model provides an electric leakage protector detector provided with a casing. The casing is provided with a switch and a display lamp, a detection connecting end is mounted at one end of the switch, a first detection connecting end is mounted at one end of the display lamp, and the detection connecting end and the first detection connecting end are connected with a circuit board through conductors. The electric leakage protector detector is capable of quickly detecting whether an electric leakage protector has a protection function or not, thereby having advantages of reliable detection result, stability and safety, simple structure and low manufacturing cost.
Description
Technical field
The utility model belongs to the electrical equipment detection technique, is specially a kind of earth leakage protective device pick-up unit.
Background technology
In the daily life in order to protect security appliance and personal safety often to use the electrical leakage protective device; But there is complex structure in the quality detection device to this series products, complex operation, the defective that cost of manufacture is high.And zero sequence current mutual inductor has been removed aborning in order to reduce manufacturing cost by the producer that has, and has only started an inner electromagnet and remove to back down mechanism's deenergization when using, and does not have any defencive function.
Summary of the invention
The purpose of this utility model provides a kind of earth leakage protective device pick-up unit, can whether defencive function be arranged the fast detecting earth leakage protective device, and testing result is reliable, stability and safety, has characteristics simple in structure, low cost of manufacture.
The purpose of this utility model is achieved through the following technical solutions: the earth leakage protective device pick-up unit; it has housing; on housing, be provided with switch and display lamp; switch one end installation and measuring link; display lamp one end is installed first and is detected link, and detection link and first detects link and is connected with wiring board by lead.
The beneficial effects of the utility model are: owing to can whether defencive function be arranged the fast detecting earth leakage protective device, testing result is reliable, stability and safety, has simple in structure, advantage of low manufacturing cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the electrical schematic diagram of Fig. 1.
Embodiment
Earth leakage protective device pick-up unit of the present utility model; it has housing 6, is provided with switch 2 and display lamp 4 on housing 6, switch 2 one end installation and measuring links 1; display lamp 4 one ends are installed first and are detected link 3, and detection link 1 and first detects link 3 and is connected with wiring board 5 by lead.Display lamp 4 other ends on the described wiring board 5 join with resistance R, adjustable resistance R1 and switch 2 respectively successively by electric wire.During use, earth leakage protective device is set in gate-dividing state, detect link 1 connects the earth leakage protective device input end by lead live wire, first detects link 3 connects the earth leakage protective device output terminal by lead zero line, then earth leakage protective device is closed a floodgate, and close a switch 2, if earth leakage protective device trips immediately, illustrate that its earth leakage protective device is qualified; If earth leakage protective device does not trip, make display lamp 4 luminous through high-power resistance R, illustrate that its earth leakage protective device is defective.Whether the utility model is owing to can have defencive function by the fast detecting earth leakage protective device, and testing result is reliable, stability and safety, has simple in structure, advantage of low manufacturing cost.The utility model not detailed description is a known technology.
