Description
Technical field
The utility model relates to a kind of verifying attachment, is specifically related to a kind of electric energy meter cell failure verifying attachment.
Background technology
Power supply department is that the electric energy metering device that the electricity consumption user is disposed is the three-phase and four-line induction type electric energy meter, when operating three-phase and four-line low-voltage electric energy table wherein one mutually or two facies units when breaking down, this electric energy meter just is in the phase shortage operating condition, lacks the electric energy record of a phase or two-phase.Owing to can't accomplish fast to find and detect, can cause a large amount of electric energy to leak meter, therefore cause the energy loss of power supply department quite serious every year.
The utility model content
The purpose of this utility model be to provide a kind of easy, volume is light and handy, sturdy and durable, number of operations unrestricted, the three-phase and four-line electric energy meter cell failure verifying attachment that wiring is simple and easy, handling safety is reliable, checkability is high is installed.
For achieving the above object, the technical solution adopted in the utility model is: a kind of electric energy meter cell failure verifying attachment, comprise verifying attachment housing, external connection, also comprise fictitious load, check start button and the check commutation knob be located in the verifying attachment housing, described fictitious load becomes the circuit of series connection with check start button, check commutation knob-shaped.
More excellent, described external connection is provided with protective sleeve outward.
And described verifying attachment housing is provided with mounting hole.
The beneficial effects of the utility model: the utility model is simple in structure, but easy, practical, volume is light and handy, sturdy and durable, the protective sleeve of external connection outside can effectively prolong the serviceable life of external connection, and number of operations without limits, need not to open former measurement seal and just can fast detect each cell failure situation with table case (cabinet) door; Need not on-the-spot charged access any load, it is reliable to detect job safety; Can in time detect and find the artificial electricity filching behavior that damages the electric energy meter internal element; Fault detect efficient height, the about cell failure that just can finish measuring apparatus in 10 seconds detects.In case adopt this verifying attachment, the power supply department relevant personnel just can be when checking meter at every turn, and simple operations is this verifying attachment once, just can in time find whether to exist fault, thereby reduce the loss of electric energy metrical; Use this syndrome check device, can in time find artificially to damage the electricity filching behavior of electric energy meter inner member; Can improve power marketing management and realize increasing strong help is provided for power supply department for extending sales; Highly versatile, can with the supporting installation of table case of coming of new, be applicable to simultaneously the operation three-phase table case carry out add-assembly.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, 2, the utility model discloses a kind of electric energy meter cell failure verifying attachment.It is in parallel with the electric energy meter loop that electric energy meter cell failure verifying attachment is connected the back by fictitious load 5 and check commutation knob 3 and check start button 2 by series circuit, and fictitious load 5, check commutation knob 3, check start button 2 are fixed in the special verifying attachment housing 4.Verifying attachment housing 4 is circumscribed with the external connection 1 that is connected with electric energy meter; in order to prolong the serviceable life of external connection 1; be provided with the protective sleeve 11 that shields on external connection 1, external connection 1 is a relation in parallel with the electric energy meter loop, and fictitious load 5 is a series relationship with tested electric energy meter unit.For easy to use, on verifying attachment housing 4, be provided with mounting hole 41, this verifying attachment can be fixed up by mounting hole 41.
As shown in Figure 3, be working circuit diagram of the present utility model.In parallel after fictitious load 5 and check start button 2, check commutation knob 3, the tested electric energy meter units in series with the electric energy meter loop.The technical parameter of this electric energy meter cell failure verifying attachment is:
1. rated voltage 0.5kV, electric current 0.5～1A
2. frequency 48～62Hz
3. environment temperature :-10 ℃～40 ℃
After certain detected unit of electric energy meter (A or B or C) is selected by check commutation knob 3, press check start button 2, fictitious load 5 in the verifying attachment forms a work loop separately with unit under test, if electric current, the potential winding of electric energy meter unit under test are all intact, then can produce a turning moment, thereby promote the dial rotation of electric energy meter; If rotating disk can't turn round, show that then the unit under test of electric energy meter has fault.By rotation check commutation knob 3, can test each unit fast respectively and whether have fault.
The utility model is simple in structure, but easy, practical, volume is light and handy, sturdy and durable, the protective sleeve 11 of external connection 1 outside can effectively prolong the serviceable life of external connection 1, and number of operations without limits, need not to open former measurement seal and just can fast detect each cell failure situation with table case (cabinet) door; Need not on-the-spot charged access any load, it is reliable to detect job safety; Can in time detect and find the artificial electricity filching behavior that damages the electric energy meter internal element; Fault detect efficient height, the about cell failure that just can finish measuring apparatus in 10 seconds detects.In case adopt this verifying attachment, the power supply department relevant personnel just can be when checking meter at every turn, and simple operations is this verifying attachment once, just can in time find whether to exist fault, thereby reduce the loss of electric energy metrical; Use this syndrome check device, can in time find artificially to damage the electricity filching behavior of electric energy meter inner member; Can improve power marketing management and realize increasing strong help is provided for power supply department for extending sales; Highly versatile, can with the supporting installation of table case of coming of new, be applicable to simultaneously the operation three-phase table case carry out add-assembly.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
