Embodiment Construction

[0017] Such as Figure 1-Figure 6 As shown, in the high-voltage protection type anti-theft power metering box, the outer cover of the metering box 1 is equipped with a protective box 12, and the metering box is placed in the protective box 12. The protective box 12 has a certain protective effect on the metering box and can avoid metering. The box is damaged, prolonging the service life of the metering box. Both sides of the protection box 12 are provided with heat dissipation holes 21. Existing metering boxes are generally made of metal materials, and various electrical appliances will generate a lot of heat during operation. After adopting the above structure, the heat can be dissipated through the heat dissipation holes 21. . A baffle plate 22 inclined downwards is fixedly connected directly above each cooling hole 21 , and the baffle plate 22 can prevent rainwater or dust from entering the protection box 12 through the air outlet. The protection box 12 includes a box bod...

Abstract

The invention discloses a high-voltage-protection type anti-theft power measuring box. The measuring box is placed in a protection box body, and a protection box has a certain protection effect on the measuring box; the side of the protection box is provided with an air outlet hole, so that emission of heat in the measuring box is facilitated; a baffle can prevent rain water or dust from entering the protection box through the air outlet hole; when a box door is closed, the box door extrudes an elastic switch to be closed, an alarm cannot ring, when the box door is opened, the elastic switch is reset, the alarm rings, and therefore the measuring box has the electricity stealing preventing function; V / V wiring is adopted by two voltage transformers, primary taps of the voltage transformers are connected to an A phase, a B phase and a C phase through fuse pipes, and the two voltage transformers can be prevented from being burned up due to overload through the high-voltage fuse pipes configured on the voltage transformers; it is guaranteed that power is continuously supplied through a configured special power transformer, and therefore the phenomenon that a circuit breaker cannot trip due to the fact that any one phase of the A phase, the B phase and the C phase is failed can be prevented.

Description

technical field [0001] The invention relates to a high-voltage protection type anti-theft power metering box. Background technique [0002] The existing high-voltage metering box lacks the overload protection function for the voltage transformer, and the power winding formed by the secondary winding of the power transformer will also lose the power supply due to the overload of the power transformer, causing the circuit breaker to fail due to Electricity can not be tripped; In addition, the existing metering box is easy to be stolen, causing loss and inconvenience to daily work. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-voltage protection type anti-theft power metering box for the above-mentioned defects. Can achieve the purpose of anti-theft. [0004] In order to solve the above-mentioned technical problems, the structural features of the present invention are: the outer cover of the metering box ...
