Abstract

The present invention discloses an improved low-voltage measurement safety protection device which comprises a protection plate, a fixed mounting plate fixedly arranged at the outer periphery of the protection plate, threading through holes arranged in the protection plate, threading check assemblies arranged in the threading through holes, a chip board arranged inside the protection plate and a conductor arranged on the inner wall of the threading through hole and is connected to the chip board. Each of the threading check assemblies comprises a check rod located in the threading through hole, a threaded rod which is fixedly connected to the check rod and is on the check rod, a screw cap fixedly arranged at the upper end of the threaded rod, and a threaded hole which is arranged in the protection plate and is on the threading through hole. The device is suitable for the tracking of repeated power theft and is installed on a removed ammeter, the whole part of the device is made of a flame-retardant insulating material PPC board, the device can withstand voltage of 400V, an electronic chip is added, the appearance is simple, the device is safe and reliable, and middle pipes sleeve exposed live and zero lines. Once the device is removed, the chip automatically sends information to an inspector receiving device.

Description

technical field [0001] The invention relates to an improved low-voltage metering safety protection device. Background technique [0002] The number of residential users involved in the daily anti-stealing work is huge. There are many users under the jurisdiction of the low-voltage electricity inspection team. In the past, illegal electricity usage and electricity theft in various places were mainly a small number of residents and individual enterprises. However, in recent years, driven by economic interests, electricity theft has gradually become ganged and expanded. During the anti-stealing personnel's inspection and processing, after the electricity-stealing user's meter is removed, the remaining empty meter provides convenience for the user to continue to steal electricity, and also increases the risk of short circuit and electric shock. Contents of the invention [0003] The purpose of the present invention is to provide an improved low-voltage metering safety protec...
