Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, and more particularly to a waterproof high-voltage power distribution cabinet for outdoor use. Background Art

[0002] Nowadays, people's life and production are inseparable from electricity, and the laying of circuits is becoming more and more diverse. In the laying of circuits, high-voltage circuit breakers, high-voltage disconnectors, high-voltage automatic reclosers and sectioners and other conversion and control equipment are often used. These devices are directly exposed to the outside world and are easily affected. Therefore, distribution cabinets are set up to protect various conversion and control equipment.

[0003] Common electrical equipment will generate heat when working. In order to ensure the normal use of the equipment, ventilation equipment will be set up for heat dissipation in the distribution cabinet. The common ventilation structure will make the inside of the distribution cabinet directly connected to the outside world and protected by a dustproof net. This structure can protect against dust and other foreign matter, but the outdoor environment is not stable. When facing rain and snow, rainwater falls along the outer wall of the cabinet and may flow directly into the distribution cabinet along the ventilation structure, causing short circuit damage to the electrical equipment after contact with water, affecting circuit safety and posing a safety hazard. Moreover, in addition to the influence of rainwater, when facing severe cold weather, Excessively cold weather outside will affect the temperature inside the distribution cabinet, and too low a temperature will affect the operation of electrical equipment. If the ventilation structure is blocked, the temperature inside the distribution cabinet will be higher than the outside, which may cause moisture in the internal air to condense on the inner wall of the cabinet and the outer casing of the electrical appliance, forming water droplets that affect the operation of the electrical equipment. In addition, in addition to the ventilation structure that may cause rainwater to enter, common cabinets provide an openable and closable protective structure through the cabinet door, and there is a gap between the common cabinet door and the cabinet body to leave space for the cabinet door to rotate, and rainwater may also flow into the distribution cabinet along the gap, causing damage to the internal electrical equipment.

A limiting frame 9 is provided in the cabinet 1, and a drying box 10 is slidably connected in the limiting frame 9. A ventilation cover 11 is provided on the drying box 10.

[0032] In this embodiment, a preservation structure is provided by the cabinet 1, and ventilation is achieved through the cooperation of the vent 3, the air guide cavity 2 and the air vent 5. When it rains outside, rainwater slides down the outer wall of the cabinet 1, and after entering the air guide cavity 2 along the vent 3, it is affected by gravity and cannot flow upward. Only the airflow will move upward along the air guide cavity 2 and flow into the cabinet 1 from the air vent 5 to achieve ventilation, and the rainwater will flow out of the air guide cavity 2 from the drain pipe 6 and will not enter the cabinet 1 to affect the high-voltage power distribution equipment.

[0033] More specifically, in severe winter weather, the sealing plate 8 is controlled to move along the sliding frame 7 so that the sealing plate 8 blocks the vent 5, preventing the flow of gas. The temperature is transferred and diffused only by the cabinet 1, thereby preventing the temperature inside the cabinet 1 from being too low and ensuring that the power distribution equipment operates at a suitable temperature. In addition, by filling the drying box 10 with drying material and then positioning the drying box 10 in the limiting frame, the drying box 10 communicates with the air in the cabinet 1 through the vent cover 11, absorbing moisture in the air and preventing the water vapor from condensing into water droplets and affecting the electrical appliances inside the power distribution cabinet 1.

[0039] Specifically, the installation slot 17 provides space and the installation frame 18 is installed into the installation slot 17, so that the dustproof net 4 blocks the vent 3 to protect the vent 3, and the installation frame 18 cooperates with the installation slot 17 through fixing bolts and can be disassembled to clean the dustproof net 4.

[0040] See also Figure 4 As a further implementation of the air guide cavity: a first guide plate 19 and a second guide plate 20 are provided in the air guide cavity 2. The first guide plate 19 and the second guide plate 20 are both inclined downward and are staggered at both ends of the air guide cavity 2.

[0041] Specifically, when the air flow flows along the air guide cavity 2, it will be blocked by the first guide plate 19 and the second guide plate 20, and needs to pass through the first guide plate 19 and the second guide plate 20 in a zigzag manner. The dust and moisture mixed in the air flow will adhere to the lower surface of the first guide plate 19 and the second guide plate 20, thereby filtering the gas.

[0042] See also Figure 3 and Figure 4As a further implementation of the vent hole: a drying plate 21 is provided at one end of the sealing plate 8, and the drying plate 21 is slidably matched with the sliding frame 7.

[0043] Specifically, when the vent 5 is used for ventilation, the drying plate 21 is slid along the sliding frame 7, which blocks the vent 5. When air flows out of the vent 5, the air is dried by the drying plate 21 and flows into the cabinet 1, thereby drying the air and preventing the influence of moisture.

[0044] See also Figure 3 As a further embodiment of the cabinet: a mounting frame 22 is provided in the cabinet 1, and a lighting lamp 23 is provided on the mounting frame 22.

The solar photovoltaic panel 24 cooperates with the battery 25, and the battery 25 cooperates with various electrical equipment.

[0047] Specifically, the solar photovoltaic panel 24 absorbs light energy and converts it into electrical energy, which is then stored in the battery 25. The battery 25 is used to power small electrical devices with low power consumption, such as the lighting lamp 23, thereby reducing power consumption.

[0048] To sum up, when the overall device is in use or running:

[0049] When the equipment is in use, the cabinet 1 provides a storage structure, and ventilation is carried out through the cooperation of the air vent 3, the air guide cavity 2 and the air vent 5, and space is provided by the mounting groove 17. The mounting frame 18 is installed in the mounting groove 17, so that the dustproof net 4 blocks the air vent 3 to protect the air vent 3 and prevent a large amount of dust or other foreign matter from entering the air guide cavity 2. The mounting frame 18 cooperates with the mounting groove 17 through fixing bolts and can be disassembled to clean the dustproof net 4. When the outside world is in rainy weather, rainwater slides along the outer wall of the cabinet 1, and after entering the air guide cavity 2 along the air vent 3, it is affected by gravity and cannot flow upward. Only the airflow will move upward along the air guide cavity 2 and flow into the cabinet 1 from the air vent 5 to achieve ventilation. When the air vent 5 is used for ventilation, the drying plate 21 is slid along the sliding frame 7 to block the air vent 5. When air flows out of the air vent 5, the gas is dried. After drying, the plate 21 flows into the cabinet 1 to dry the gas and prevent the influence of moisture. Moreover, when the air flow flows along the air guide cavity 2, it will be blocked by the first guide plate 19 and the second guide plate 20, and needs to pass through the first guide plate 19 and the second guide plate 20 in a zigzag manner. The dust and moisture mixed in the air flow will adhere to the lower surface of the first guide plate 19 and the second guide plate 20, and then flow downward, thereby filtering the gas. The rainwater gathered below will flow out of the air guide cavity 2 from the drain pipe 6 and will not enter the cabinet 1, avoiding affecting the high-voltage power distribution equipment. Moreover, the recessed frame 13 provides space. When the cabinet door 12 is closed, the inner wall of the cabinet door 12 will cooperate with the recessed frame 13 to facilitate close contact, avoiding gaps between the cabinet door 12 and the cabinet 1, and the cooperation of the waterproof pad 14 and the sealing pad 15 further provides a sealing effect to prevent external dust and rainwater from entering the cabinet 1.

[0050] In severe cold weather in winter, the sealing plate 8 is controlled to move along the sliding frame 7 so that the sealing plate 8 blocks the vent 5 to prevent the flow of gas. When the cabinet door 12 is closed, the insulation plate 16 will sink into the inner side of the recessed frame 13 and cooperate with the waterproof pad 14 and the sealing pad 15 to form an insulation structure to prevent the temperature from being lost from the gap of the cabinet door 12. The temperature is transferred and diffused only by the cabinet body 1, thereby preventing the temperature inside the cabinet body 1 from being too low and ensuring that the power distribution equipment operates at a suitable temperature. In addition, by filling the drying box 10 with drying material and then placing the drying box 10 in the limiting frame for positioning, the drying box 10 communicates with the air in the cabinet body 1 through the vent cover 11 to absorb moisture in the air. The drying plate 21 also provides a drying effect. When used in an environment with high humidity, the drying material and the drying plate 21 in the drying box 10 need to be replaced in time to ensure the stability of the drying effect. In addition, when using the distribution cabinet, the solar photovoltaic panel 24 absorbs light energy and converts it into electrical energy, which is then stored in the battery 25. The battery 25 supplies power to small electrical equipment with low power consumption, such as the lighting lamp 23, to reduce power consumption. The mounting frame 22 is supported by the lighting lamp 23 to install the lighting, which provides lighting for convenient observation of the internal distribution equipment.
