Intelligent electric meter protection device with function of preventing malicious damage

Abstract

The invention discloses an intelligent electric meter protection device with a function of preventing malicious damage, and the device comprises an active detection assembly and a maintenance disassembly assembly, the active detection assembly comprises a protection shell, a sealing shell, a sealing ring, a base cylinder, a base spring, a detection frame, a magnetic ring and an extrusion column, and the sealing shell is matched with the protection shell. The base cylinder communicates with the center of the bottom of the outer wall of the protective shell. According to the invention, through the active detection assembly and the maintenance and disassembly assembly, on one hand, the contact position of the protective shell and the sealing shell can be protected, and once an unauthorized sealing shell moving action is generated, dye spraying can be performed on the protective shell and the sealing shell, so that direct observation and maintenance are facilitated, and subsequent tracing is facilitated; and the working safety is high.

Description

technical field [0001] The invention belongs to the technical field of electric meters, in particular to an intelligent electric meter protection device with the function of preventing malicious damage. Background technique [0002] The abbreviation of watt-hour meter is an instrument used to measure electric energy, also known as watt-hour meter, fire meter, electric energy meter, kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. [0003] In order to prevent users from modifying the parameters of the electric meter or damaging the electric meter, lead seals are installed on the current smart electric meters. If the electric power company finds that the lead seal is damaged, it will be considered as illegal damage by the user, and the user will be held accountable. In residential areas, multiple meters are placed in one meter box, which is usually open. If there is a conflict between neighbors (meter users), the lead seal of the ot...

[0003] In order to prevent the user from modifying the parameters of the meter or damaging the meter, lead seals are installed on the current smart meters. If the power company finds that the lead seal is damaged, it will be considered as illegal damage by the user, and the user will be held accountable. In residential areas, multiple meters are placed in one meter box, and the meter box is usually open. If there is a conflict between neighbors (meter users), the lead seal of the other party’s meter may be damaged, so that the power company will The other party will be held accountable, that is, the other party was framed, but it cannot be proved that it was not damaged by itself. Secondly, when the meter is damaged, it is impossible to quickly call the police, and the practicability is poor.
