The utility model discloses a simple tester for a household residual-current circuit breaker. The tester comprises a housing, a plug and an indicator light, the plug is connected with the housing through a lead, and the tester is characterized in that the housing is provided with the indicator light, a button, a double-throw switch and a resistor, an earth wire E of the plug is connected with the button, the resistor and a fixed contact of the double-throw switch through a lead in series, the earth wire E of the plug is connected with the indicator light in series through a lead, and two movable contacts of the double-throw switch are connected with a phase line L and a null line N of the plug through leads respectively. The simple tester for the household residual-current circuit breaker is simple in structure and convenient to use, can accurately detect whether the household residual-current circuit breaker is normal without wiring, and is safe and reliable, improving the accuracy rate of detection.
Description
Technical field
The utility model relates to a kind of proving installation of residual current circuit breaker, specifically a kind of family expenses residual current circuit breaker easily-testing device.Be applied to general resident's home test family expenses residual current circuit breaker.
Background technology
At present, general family expenses resident family is when checking whether residual current circuit breaker correctly works, owing to be subjected to condition restriction, generally can only use himself test button, residual current circuit breaker is tested, this test can only check the whether normal of isolating switch self subelement, can not simulate phase line ground connection whole residual current circuit breaker system situation is detected.When general family expenses residual current circuit breaker is installed and used, require " with 0.5-1 kilo-ohm or 3 correct operations of 100 watts of bulb ground connection experiments, the method experiment that can not directly touch earthing device with phase line ".Detect with resistance and bulb, there are bigger potential safety hazard in wiring complexity, troublesome poeration, and non-specialized-technical personnel are difficult to operation.
Summary of the invention
Whether normally it is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and need not wiring, safe and reliable, can detect family expenses residual current circuit breaker family expenses residual current circuit breaker easily-testing device.
In order to reach above purpose, the technical scheme that the utility model adopts is: this family expenses residual current circuit breaker easily-testing device, comprise housing, plug and pilot lamp, plug is connected with housing by lead, it is characterized in that: described housing is provided with pilot lamp, button, double-throw switch and resistance, the ground wire E of plug connects with the stationary contact of button, resistance and double-throw switch by lead, the ground wire E of plug connects with the stationary contact of pilot lamp, double-throw switch by lead, and two moving contacts of double-throw switch are connected with zero line N with the phase line L of plug by lead respectively.
The resistance of described resistance is 0.8 kilo-ohm.
The beneficial effects of the utility model are: simple in structure, easy to use, whether normal, need not wiring, safe and reliable if can accurately detect the family expenses residual current circuit breaker, improved the accuracy rate that detects.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Among the figure: 1, housing; 2, pilot lamp; 3, button; 4, double-throw switch; 5, plug; 6, resistance.
Embodiment
Make the utility model with reference to Fig. 1, Fig. 2.This family expenses residual current circuit breaker easily-testing device, comprise housing 1, plug 5 and pilot lamp 2, plug 5 is connected with housing 1 by lead, it is characterized in that: described housing 1 is provided with pilot lamp 2, button 3, double-throw switch 4 and resistance 6, the ground wire E of plug 5 connects with the stationary contact of button 3, resistance 6 and double-throw switch 4 by lead, the ground wire E of plug 5 connects with the stationary contact of pilot lamp 2, double-throw switch 4 by lead, and two moving contacts of double-throw switch 3 are connected with zero line N with the phase line L of plug 5 by lead respectively.
The resistance of described resistance 6 is 0.8 kilo-ohm.
When using the utility model that the family expenses residual current circuit breaker is tested; utilize the earth terminal E of family expenses three-phase socket and line end L mutually; the plug 5 of test usefulness is inserted on the family expenses three-phase socket; if phase line L, ground wire E wiring are correct, then pilot lamp 2 is luminous, illustrates that the loop is correct; press the button 3; be equivalent to serial connection one resistance 6 between phase line L in will detecting the residual current circuit breaker protection domain and the earth terminal E, simulate one 0.8 kilo-ohm resistance eutral grounding, whether the test residual current circuit breaker is moved and is met the requirements.Because household socket mounting process and other reasons may cause phase line L, zero line N in the three-phase socket out of position, switch to eliminate the influence of this situation with 4 pairs of loops of double-throw switch for this reason.Experimental implementation is as follows:
(1), plug 5 directly inserts in the family expenses three-phase socket, pilot lamp 2 is luminous, presses the button 3, the action of family expenses residual current circuit breaker illustrate that residual current circuit breaker is normal, illustrates that residual current circuit breaker is defective if residual current circuit breaker is failure to actuate;
(2), plug in after 5, if pilot lamp 2 does not work, double-throw switch 4 is switched to the another location, pilot lamp 2 is luminous, by the test of (1) step; (3), switch double-throw switch 4 after, pilot lamp 2 still not luminous then loop is obstructed, illustrates that E is earth-free in the three-phase socket, then the utility model can not use.
The utility model is simple in structure, easy to use, need not wiring, safe and reliable, can satisfy family expenses residual current circuit breaker simple test requirement.
Claims (2)
1. family expenses residual current circuit breaker easily-testing device, comprise housing (1), plug (5) and pilot lamp (2), plug (5) is connected with housing (1) by lead, it is characterized in that: described housing (1) is provided with pilot lamp (2), button (3), double-throw switch (4) and resistance (6), the ground wire E of plug (5) is by lead and button (3), the stationary contact series connection of resistance (6) and double-throw switch (4), the ground wire E of plug (5) is by lead and pilot lamp (2), the stationary contact series connection of double-throw switch (4), two moving contacts of double-throw switch (3) are connected with zero line N with the phase line L of plug (5) by lead respectively.
2. family expenses residual current circuit breaker easily-testing device according to claim 1, it is characterized in that: the resistance of described resistance (6) is 0.8 kilo-ohm.
