The invention provides an electricity-stolen prevention device of a kilowatt-hour meter, and the electricity-stolen prevention device is used for preventing the electricity of the kilowatt-hour meter from being stolen; the kilowatt-hour meter is provided with a microswitch; the electricity-stolen prevention device of the kilowatt-hour meter comprises an upper cover, an end cover, an elastic element, a trigger part and a button, wherein the trigger part comprises a sleeve part and a trigger part; the upper cover is provided with a first containing space and a containing groove which is provided with a central shaft; the microswitch is arranged in the first containing space and deviates from the central shaft; the end cover can be combined with or separated from the upper cover; and the elastic element is arranged in the containing groove. The button is connected with the sleeve part; when the end cover is combined with the upper cover, the trigger part is contacted with the microswitch; and when the end cover is separated from the upper cover, the trigger part is disconnected with the microswitch.
Description
technical field [0001] The invention relates to the field of electricity, in particular to an anti-stealing device for a watt-hour meter. Background technique [0002] At present, most of the widely used watt-hour meters have the protection function of anti-stealing, so as to prevent the thieves from stealing electricity by connecting loads in front of the watt-hour meters or short-circuiting the watt-hour meters. In the current electricity meter with anti-stealing function, the usual method is to open the cover to detect, that is, to configure a detection switch on the button of the meter cover. When the electricity thief needs to steal electricity, he must try to open it. The cover body, at this time, the detection switch triggers a monitoring device, such as a camera, etc., and the electricity stealing behavior of the electricity thief can be monitored through the monitoring device. [0003] Due to the detection of the opening of the end cover, in general, the matching s...
