Description

Technical Field

[0001] The present invention relates to the technical field of power distribution, and particularly to an electric energy metering box for power distribution equipment. Background Art

[0002] An electric energy metering box is a key device for measuring and recording the electric energy consumed by users. It is usually installed near power distribution equipment (such as transformers, power distribution cabinets, etc.), connected to the user's power supply line, accurately records the power consumption through the built-in electric energy meter, and provides a basis for electricity bill settlement. Modern electric energy metering boxes may also integrate various functions, such as load management, power factor correction, and remote data transmission.

[0003] An electric energy metering box usually needs to record the data of the internal electric energy meter to ensure accurate electricity measurement, monitor the electricity consumption situation, and facilitate subsequent data analysis and management. By recording the data of the electric energy meter, the accuracy of electricity bill calculation can be ensured, and disputes over fees caused by incorrect readings can be avoided. Regularly recorded data helps monitor power usage patterns and identify abnormal electricity consumption behaviors, such as sudden increases or decreases in electricity, which may indicate equipment failures or other problems.

[0004] Currently, it is generally the case that staff members regularly go to the site to copy the readings of the electric energy meter. In some abnormal situations, the electric energy metering box may generate electric sparks or cause other problems, such as short - circuit faults, poor contacts, etc. Staff members cannot discover and handle these problems in a timely manner. For example, in the event of a short - circuit in the circuit, that is, an accidental direct contact between conductors, the current will increase sharply, far exceeding the normal range. At this time, the protection device (such as a circuit breaker) inside the electric energy metering box should immediately act to cut off the power supply. However, if the protection measures fail or the response is not timely, a large amount of electric sparks may be generated in a short period of time, accompanied by a burnt smell and even a risk of fire. If there are problems such as looseness, oxidation, or contamination at various electrical connection points inside the electric energy metering box, the contact resistance will increase. The high impedance will generate heat when current passes through, and in extreme cases, an arc discharge phenomenon will occur, manifested as visible electric sparks, posing a risk of fire. Summary of the Invention

[0005] In view of this, the present invention provides an electric energy metering box for power distribution equipment, which can overcome the disadvantages that the electric energy metering box may generate electric sparks or cause other problems, such as short - circuit faults, poor contacts, etc., in some abnormal situations.

The guiding box 183 can guide the first sealing block 181 to make the movement of the first sealing block 181 more stable.

[0035] The staff member opens the box door 2, then installs the electrical components on the mounting plate 3 and installs the electricity meter inside the box body 1. The partition 4 separates the electrical components from the electricity meter. Then, the box door 2 is closed, and the sealing strip 171 will enter the sealing groove 172. The interior of the box body 1 can be ventilated through the ventilation opening 5. The dust-proof net 164 can block the dust from the outside world and prevent the dust from entering the box body 1. The staff member can control the first solenoid valve 11 to open, then inject inert gas into the gas compression tank 9 through the intake pipe 10, and then control the first solenoid valve 11 to close. The second solenoid valve 13 is also in the closed state, so the inert gas in the gas compression tank 9 will not leak. The lead screw motor 6 can drive the slide plate 7 to move downward, and the slide plate 7 drives the vision camera 8 to move downward. The vision camera 8 can photograph the electrical components and the electricity meter inside the box body 1, and can read the value on the electricity meter and record the value in the controller 14. If the vision camera 8 photographs an electric spark, it indicates that there is a fire risk inside the box body 1. At this time, the vision camera 8 will send a signal to the controller 14, and the controller 14 will control the lead screw motor 6 to continuously drive the slide plate 7 to move downward. The downward movement of the slide plate 7 will contact the contact plate 167 and push the contact plate 167 downward. The contact plate 167 drives the moving plate 166 to move downward, and the moving plate 166 drives the sealing frame 162 to move downward. During the downward movement of the sealing frame 162, it will contact the top of the rubber plate 165 and seal the ventilation opening 5. Subsequently, the controller 14 will control the electromagnet 173 to be energized, and the electromagnet 173 will suck the box door 2 to make the sealing strip 171 and the box door 2 in close contact, improving the sealing performance inside the box body 1. Subsequently, the controller 14 will control the air pump 153 to work. The air pump 153 extracts the air inside the box body 1 through the air collecting hood 151, discharges the oxygen inside the box body 1, and reduces the conditions for a fire to occur inside the box body 1. At the same time, the controller 14 will control the second solenoid valve 13 to open, and the inert gas in the gas compression tank 9 enters the box body 1 through the outlet pipe 12, diluting the oxygen concentration inside the box body 1 so that a fire cannot occur inside the box body 1. The sealing frame 162 has sealed the ventilation opening 5, the sealing strip 171 has sealed the gap between the box body 1 and the box door 2, and the first sealing block 181 and the second sealing block 182 have sealed the opening 168, thereby being able to prevent the loss of inert gas inside the box body 1 and enabling the inert gas to continuously inhibit combustion.
