The invention provides a combined-type electricity box for temporary use. The electricity box includes a cuboid box body, a front side face of which is provided with a box gate; an electric-energy meter fixed in the box body; a disconnecting switch, an input terminal of which is connected with an output terminal of the electric-energy meter; a three-phase electricity-leakage protector, an input terminal of which is connected with an output terminal of the disconnecting switch; a single-phase electricity-leakage protector, an input terminal of which is connected with the output terminal of the disconnecting switch and a ground wire; and a fixing hardware fitting which is arranged at a rear side face of the box body and used for fixing the box body temporarily on a telegraph pole. The combined-type electricity box for temporary use targets at a characteristic that times of temporary power use are comparatively concentrated and at the same time, according to demands of users and a standardized process for installation of a meter box, the combined-type electricity box for temporary use is provided so that it is more convenient for temporary power use of the users and construction and installation are simpler and faster.
Description
technical field [0001] The present invention relates to an electricity metering device, in particular, the present invention particularly relates to a combined temporary electricity box. Background technique [0002] Temporary power consumption is a power supply method that the power supply department classifies according to the power consumption period and is different from the formal power consumption. In rural areas, drilling wells for irrigation, gatherings and performances, infrastructure construction, etc. will mostly cause temporary power consumption. In the case of temporary power consumption, if ordinary power metering boxes are used for meter installation and connection, the following problems may exist: [0003] The wiring is time-consuming and laborious, the installation quality is poor, and the wiring is not standardized. [0004] In order to reduce costs, individual users do not install protective equipment. [0005] The quality of equipment purchased by user...
