Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to an upright intelligent monitoring device for a high-voltage cable grounding system. Background Art

[0002] High-voltage cables are usually single-core structures. During the operation of the cable, the metal sheath of the cable will generate an induced voltage due to the current flowing through it. The magnitude of the induced voltage is related to factors such as the length of the cable and the magnitude of the current. When a short circuit occurs during the operation of the cable or an overvoltage occurs due to a lightning strike, the induced voltage on the metal sheath of the cable will increase significantly, and the outer sheath of the cable will be broken down, thus affecting the safe operation of the cable. Therefore, it is necessary to install a grounding system monitoring device on the cable according to the actual situation, monitor the voltage and current values ​​on the metal sheath of the cable in real time when the cable is running, and comprehensively judge the operating conditions of the cable.

[0003] Most of the metal sheath monitoring devices currently available on the market have the following problems:

[0004] 1. The monitoring method is too single, mainly focusing on the voltage and current monitoring of the sheath, lacking auxiliary monitoring information such as temperature, humidity, video images, etc., which leads to misjudgment of the operating conditions of the high-voltage cable;

[0005] 2. Most grounding boxes on the market can only achieve IP66 protection level, and can generally only be used in outdoor occasions. However, due to the complex and changeable actual installation and operation of cables and wires, and the monitoring devices being immersed in water, the protection level is not enough to limit their use occasions.

[0006] Therefore, an intelligent monitoring device for an upright high-voltage cable grounding system is proposed. Utility Model Content

[0007] The utility model aims to provide an upright intelligent monitoring device for a high-voltage cable grounding system.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] An upright high-voltage cable grounding system intelligent monitoring device, comprising:

[0010] An upright cabinet body and a cabinet door mounted on a front surface of the upright cabinet body;

[0011] A trapezoidal seat is fixed on the top of the upright cabinet, a mounting groove is provided on the inclined surface of the trapezoidal seat, and a photovoltaic panel is installed in the mounting groove;

[0012] A GPS antenna and a 4G antenna are installed on the top of the trapezoidal seat;

[0013] The vertical cabinet is equipped with a collection unit device, a cross-connected copper busbar assembly, a temperature and humidity sensor, a tilt sensor, a monitoring camera, and a door magnetic sensor in sequence.

[0014] Preferably, the upright cabinet is manufactured by sheet metal bending and full-welding waterproof welding technology.

[0015] Preferably, the surface of the upright cabinet is sprayed with an outdoor anti-corrosion coating, and the interior thereof is sealed using a fixed-point glue-pouring process.

[0016] Preferably, the photovoltaic panel has a built-in battery, and the battery is electrically connected to the collection unit device, the temperature and humidity sensor, the tilt sensor, the monitoring camera, and the door magnetic sensor.

[0017] Preferably, waterproof silica gel is injected into the connection between the installation groove and the photovoltaic panel.

[0018] Preferably, a first L-shaped receiving plate is connected to the rear end of the collection unit device, and the first L-shaped receiving plate is connected to the inner wall of the upright cabinet through a first fixing bolt.

[0019] Preferably, the monitoring camera is installed at the bottom of a second L-shaped receiving plate, and the second L-shaped receiving plate is connected to the inner wall of the upright cabinet through a second fixing bolt.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The utility model installs a temperature and humidity sensor and a monitoring camera inside the upright cabinet. With the cooperation of the temperature and humidity sensor and the monitoring camera, the temperature and humidity information and image information inside the upright cabinet can be sent to the outside in a timely manner, thereby avoiding misjudgment of the operating condition of the high-voltage cable and improving the overall work efficiency.

[0022] In addition, by installing an inclination sensor and a door magnetic sensor inside the upright cabinet, the inclination sensor and the door magnetic sensor can be used to monitor whether the upright cabinet moves and whether its door is opened, thereby greatly improving the anti-theft performance of the upright cabinet and providing higher security.

[0023] Since the upright cabinet is made of sheet metal bending and full-welding waterproof welding technology, and the surface of the upright cabinet is sprayed with outdoor anti-corrosion coating, the interior adopts a fixed-point glue filling and sealing process, and waterproof silicone is injected at the connection between the installation groove and the photovoltaic panel, the waterproof performance of the upright cabinet is greatly improved, and the overall applicability is improved.

[0024] The utility model can disassemble the collection unit device by disassembling the first fixing bolt, and similarly, can disassemble the monitoring camera by disassembling the second fixing bolt. Therefore, the utility model facilitates the maintenance of the collection unit device and the monitoring camera, and improves the overall work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
