Embodiment 1

[0037] see figure 1 and figure 2, the embodiment of the present invention provides a safe anti-theft electric energy meter box, including a test button 105, the test button 105 is a leakage test button of a leakage protector connected to the metering circuit of the meter box, wherein it also includes an identity authentication switch 103, Relay A102, relay B104 and door opening sensor 101; the door opening sensor 101 is connected in series with the coil of relay A102, the normally open contact of relay A102, identity authentication switch 103 and the coil of relay B104 are connected in series to form the driving circuit of relay B104, and the test button 105 It is connected in parallel with the normally closed contact of relay B104 to form an execution circuit; the identity authentication switch is usually closed or the identity authentication switch is a normally closed switch.

[0038] Wherein, the identity authentication switch 103 is an infrared remote control switch, an...

Embodiment 2

[0044] see figure 1 and Figure 6 , the embodiment of the present invention provides a safe anti-theft electric energy meter box, including a test button 105, the test button 105 is a leakage test button of a leakage protector connected to the metering circuit of the meter box, wherein it also includes an identity authentication switch 103, Relay A102, relay B104 and door opening sensor 101; the door opening sensor 101 is connected in series with the coil of relay A102, the normally open contact of relay A102, identity authentication switch 103 and the coil of relay B104 are connected in series to form the driving circuit of relay B104, and the test button 105 It is connected in parallel with the normally closed contact of relay B104 to form an executive circuit;

[0045] Wherein, the difference from Embodiment 1 is that the identity authentication switch is a contact switch, such as Figure 6 As shown, the contact switch is arranged in the lock core of the open lock of the ...

Embodiment 3

[0051] On the basis of Embodiment 1 and Embodiment 2, an electromagnetic lock 106 can also be added, see image 3 , Figure 4 and Figure 5 The specific scheme is: a safe anti-theft electric energy meter box, including a test button 105, the test button 105 is a leakage test button of a leakage protector connected to the metering circuit of the meter box, wherein it also includes an identity authentication switch 103, a relay A102, Relay B104 and door opening sensor 101; the door opening sensor 101 is connected in series with the coil of relay A102, the normally open contact of relay A102, identity authentication switch 103 and the coil of relay B104 are connected in series to form the drive circuit of relay B104, the test button 105 and relay B104 The normally closed contacts of the relay A102 are connected in parallel to form an execution circuit; the driving circuit of the relay A102 is also connected with the control circuit of an electromagnetic lock 106.

Abstract

The invention discloses a safe anti-electric-theft electric energy meter case which comprises a housing, a housing door and a master lock. The safe anti-electric-theft electric energy meter case further comprises an electromagnetic lock. The electromagnetic lock comprises a lock body which is arranged on the housing, and an adsorption iron plate which is used in cooperation with the lock body. The adsorption iron plate is movably arranged on the housing door through a drawing mechanism. The safe anti-electric-theft electric energy meter case is advantageous in that the electric energy meter case is provided with an identity authentication switch; when a user opens the electric energy meter case privately, an electric leakage protector is started, thereby switching off a power supply line, preventing private line connection by the user, and furthermore eliminating potential safety hazards.

Description

technical field [0001] The invention relates to anti-stealing equipment, in particular to a safe anti-stealing electric energy meter box. Background technique [0002] In order to prevent electricity theft, the power supply department generally takes measures to put the meter into the meter box and lock the door of the meter box with an open mechanical lock to prevent other people from opening it at will. The existing open lock has a simple structure. , it is easy to be damaged and opened by people, especially in some areas where the supervision of the meter box is not in place, it is often opened by the user privately, the line is overlapped, and the electric energy is stolen. The meter box cannot play a safe and effective role in preventing electricity theft. Contents of the invention [0003] In order to solve the problems of poor anti-stealing effect of the traditional electric meter box, the present invention provides an electric meter box capable of safely and effec...
