Electricity larceny prevention junction box

Abstract

The invention relates to the technical field of junction boxes, and discloses an electricity larceny prevention junction box which comprises a box body, a box cover, a detection mechanism, a display screen, a counting chip and a power supply, wherein the box cover is connected to the box body in an openable manner; the display screen, the counting chip and the power supply are arranged in the boxbody; the display screen is used for displaying uncovering time and uncovering times; the display screen and the counting chip are electrically connected with the power supply respectively; the display screen is connected with the output end of the counting chip; the detection mechanism comprises a first conductive section arranged on the box body, a second conductive section and a third conductive section arranged on the box cover; the first conductive section is connected with the input end of the counting chip; the second conductive section is connected with a power supply; and the first conductive section is not connected with the second conductive section. When the box body is covered with the box cover, the third conductive section makes contact with the first conductive section andthe second conductive section to conduct a circuit, the opened date and frequency of the junction box can be checked, and therefore electricity larceny prevention investigation work can be carried outin time, the electricity larceny investigation effect is improved, and the junction box has important practical significance in field work of electricity utilization inspection.

Description

Technical field[0001]The invention relates to the technical field of junction boxes, in particular to an anti-theft junction box.Background technique[0002]The electric power department measures the electric energy consumed in the circuit through the electric energy metering device at the user's power access terminal, so as to count the user's electricity consumption. For example, the electric energy meter. The electric energy metering joint junction box is a special junction box in the standard wiring of the electric energy metering device. The industry has a wide range of applications. It can be used to connect meters or instruments to the secondary circuit in operation, complete a variety of different items of load test or electricity inspection, replacement of electric energy meters, etc., and it can be safe under load Replacement or on-site inspection of electrical equipment such as electric energy meters, electrical meters, and relay protection ensures the safety of personal op...

Problems solved by technology

However, the cost of this patent is high, and once the junction box cover is removed, the ammeter cannot be used, and the ammeter needs to be replaced, and it is not conducive to the staff to carry out load testing or electricity inspection through the junction box

Moreover, if the process is reversible, it can be restored by installing the junction box cover back to its original position, so the electricity stealing cannot be curbed. The electricity thief can restore the box cover to its original state after changing the wiring, and the electricity inspectors will not be able to find abnormalities.
