Electromagnetic locking ammeter and locking control method

Abstract

The invention relates to the field of electricity meter structures, in particular to an electromagnetic locking electricity meter and a locking control method. The use of an external lead seal or a lock can be avoided, and the safety of the electricity meter is improved. The electromagnetic locking electricity meter comprises an electricity meter box, a main lock pin, locking devices and a controldevice. The electricity meter box comprises a box body and a box cover, and the main lock pin, the locking devices and the control device are arranged in the box body. The main lock pin is clamped tothe box cover and is in sliding connection with the box body, and the main lock pin is provided with a plurality of lock holes in the length direction. The number of the locking devices and the number of the lock holes are the same. Each locking device comprises a magnet and an auxiliary lock pin which are fixedly connected, the auxiliary lock pins are inserted into the lock holes, and the locking devices are connected with the box cover through springs. The control device comprises an electromagnet and a controller, the electromagnet is matched with the positions of the locking devices, andthe electromagnet is connected with the controller. The electricity meter is used in the locking control method of the electromagnetic locking electricity meter.

Description

technical field [0001] The invention relates to the field of electric meter structures, in particular to an electromagnetic locking electric meter and a locking control method. Background technique [0002] The electric energy meter is a metering device for the quantity of electric energy used. In order to ensure that the electric energy meter will not be artificially opened to interfere with the measurement, the metering junction box of the electric energy meter needs to be packaged to prevent opening, and it is generally sealed with a lead seal. At present, the lead seals are all one-time lead seals. At present, every time the power system opens the watch box cover for maintenance, it is necessary to re-package the lead seal and count the number of the lead seal. This mode wastes materials and manpower, and the management is not good. fine.

At present, the lead seals are all one-time lead seals. At present, every time the power system opens the watch box cover for maintenance, it is necessary to re-package the lead seal and count the number of the lead seal. This mode wastes materials and manpower, and the management is not good. fine

[0003] Existing conventional locks need to be opened by a key, and the physical key is not easy to manage and carry by the operator. If the lock is placed externally, it is easy to be damaged or rusted
