The invention discloses an electric energy meter metering box protection device, belonging to the technical field of power facilities. The electric energy meter metering box protection device comprises a metering box body and a recovery mechanism, wherein the metering box body comprises a box body and a box door, a rotating shaft is fixed arranged on the box body, and a sleeve is fixedly arrangedon the box door; the recovery mechanism comprises a first reset torsional spring and a first damping assembly; the first reset torsional spring is connected with the rotating shaft and the sleeve respectively, so that the box door has a tendency of rotating relative to the box body and enclosing the open end; and the first damping assembly comprises two first damping rings, and the two first damping rings are fitted to each other and are used for limiting a rotational speed of the box door relative to the box body. The electric energy meter metering box protection device provided by the invention can automatically close the box door and enclose the open end of the box body, ensures that an electric energy meter is positioned in a relatively enclosed environment, effectively prevents the electric energy meter from being exposed to the rain, damaged by animals and the like due to mistakes of the staff, and effectively prolongs the service life of instruments such as the electric energy meter.
Description
technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a protection device for a metering box of an electric energy meter. Background technique [0002] The energy meter metering box is the whole of measuring instruments and auxiliary equipment necessary for measuring electric energy, including electric energy meters, voltage for metering, current transformers and their secondary circuits, electric energy metering screens, cabinets, boxes, etc. [0003] In actual use, the metering box of the electric energy meter is placed in a natural environment. In order to prevent damage to the electric energy meter, etc., the door of the metering box needs to be closed. However, the staff may forget to close the box door for some reasons, causing the electric energy meter in the metering box to be easily damaged by rain, animals, etc. Contents of the invention [0004] The purpose of the present invention is to provide a pro...
