Description

Technical Field

[0001] The present invention belongs to the technical field of switch cabinets, and in particular relates to an electric high and low voltage switch cabinet and a use method thereof. Background Art

[0002] Electric power high and low voltage switchgear is equipment used in power systems to provide electrical protection, control and distribution functions. They are usually used in power substations, distribution rooms and other places, and are widely used in power distribution and control in industrial, commercial and civil buildings. According to the voltage level, the switchgear can be divided into high-voltage switchgear and low-voltage switchgear. The high-voltage switchgear is used to receive and distribute electricity higher than 1kV (generally 3kV, 6kV, 10kV, 35kV and above voltage levels), and provides switching, protection, monitoring and control functions. Its main purpose is to switch and protect high-voltage lines and equipment in power systems. The low-voltage switchgear is used to handle AC or DC power below 1kV. Common low-voltage switchgear voltage levels are 380V, 400V, 690V, etc. Low-voltage switchgear is widely used in industrial automation, electrified buildings and power distribution systems of commercial facilities.

[0003] Electric high and low voltage switchgear is a vital equipment in the power system. Its functions include current switching, load control, fault protection, etc. High voltage switchgear is mainly used for the distribution and protection of high voltage power, while low voltage switchgear is widely used in the control and distribution of low voltage power systems. Choosing the right switchgear can improve the safety and reliability of the power system.

[0004] Some invention patents in the field of switchgear technology are disclosed in the prior art. Among them, the invention patent with application number CN202010095606.3 discloses an electric high and low voltage switchgear, which solves the problem that in the current rapid development of cities, with the increasing number of high and low voltage switchgear, the limited land area in the city is occupied by various electric high and low voltage switchgear, which is not conducive to the optimal use of space, and these switchgears are easy to become carriers of small advertisements and become a "source of pollution" affecting the urban environment; therefore, the development of cities now urgently needs an underground high and low voltage switchgear, and the existing underground high and low voltage switchgear cannot realize the lifting of the switchgear body, which is inconvenient for workers to connect electricity and repair, and the current switchgear only uses the rear and two sides of the box body, and the utilization rate of the box body is low, resulting in waste of space.

[0005] Among them, the invention patent with application number CN202410491899.5 discloses an electric high and low voltage switch cabinet. By setting a power-off structure, the internal circuit can be powered off when a leakage fault occurs in the circuit inside the cabinet. At the same time, by setting an adjustment structure, the threshold of the power-off structure can be adjusted before use according to whether it is a high-voltage or low-voltage line, so that it has a wider range of applications and is more in line with practical applications. In addition, the switch cabinet can open the heat dissipation window synchronously when the circuit is powered off by setting a heat dissipation component, thereby improving the heat dissipation effect and helping the circuit to dissipate heat quickly.

[0006] When the above two existing technologies are used outdoors, there is a need to carry out maintenance inside the switch cabinet on rainy days. Since both of them lack rainproof mechanisms, rainwater will float into the cabinet when the cabinet door is opened for maintenance. After the rainwater enters the cabinet, it may cause internal electrical equipment (such as circuit breakers, switches, busbars, etc.) to short-circuit. Especially in high-voltage electrical equipment, moisture may cause insulation failure between equipment and generate electric arcs. In severe cases, it may cause equipment damage or fire. There are usually insulating materials inside the power switch cabinet, such as insulating gaskets, insulating boards, etc. If rainwater enters the cabinet, these materials may become damp, resulting in a decrease in insulation performance and an increased risk of electric shock or electrical failure.

[0007] Based on this, the present invention designs an electric high and low voltage switch cabinet and a method of using the same to solve the above problems. Summary of the invention

[0027] A method for using a power high and low voltage switch cabinet comprises the following steps:

[0028] S1. When the high and low voltage switchgear cabinets need to be inspected on rainy days, the motor is first used to drive the connected rotating plate to rotate and erect, which will drive the adjusting wheel to rotate accordingly. The adjusting wheel will mesh with the fixed annular rack, thereby driving the adjusting wheel to rotate, so that the adjusting wheel drives the worm to rotate, and the worm drives the worm wheel to rotate, so that the rotating shaft connected to the worm wheel rotates, thereby driving the rain shield to rotate and block the front side of the switchgear cabinet;

[0030] S3. Then the cabinet door can be opened to inspect and repair the switch cabinet. When the electrical components need to be replaced, the push-pull frame is pulled. When the storage plate is completely moved out, the spring drives the connected retractable rack to move, thereby driving the storage plate connected to the retractable gear to rotate. With the elastic curtain pulled open, a position for placing electrical components and tools can be formed, which is convenient for placing electrical components and tools during maintenance.

[0031] S4. When the motor needs to be repaired, the protective cover is pulled up and rotated to remove the protective cover so that the motor can be repaired. After the repair is completed, the protective cover is pulled up and rotated again. Under the action of the tension spring, the protective cover is covered on the motor seat to protect the motor.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0033] 1. In the present invention, when the switch cabinet is inspected and repaired on rainy days, rain shields and side baffles are provided to block rain above the switch cabinet door, effectively blocking most of the rainwater falling from the top and sides, preventing rainwater from directly flowing into the cabinet body, reducing the impact of moisture on electrical components in the cabinet, and extending the service life of the equipment. When inspection and repair are carried out on rainy days, the waterproof measures of the equipment can ensure that the electrical equipment in the switch cabinet is not affected by rainwater, thereby reducing the risk of electric shock caused by failure or leakage of electrical equipment, and effectively reducing the safety hazards of operators.

[0034] 2. In the present invention, by setting up a transmission mechanism and a push-pull mechanism, it is possible to achieve that when the rotating plate is rotated and lowered, the rain shield and the side baffles are automatically retracted without manual intervention, which greatly improves work efficiency and avoids unnecessary obstructions and space occupation. It can not only improve the convenience and safety of operation, but also effectively prevent rainwater from entering the switch cabinet, protect electrical equipment from environmental influences, and at the same time improve the reliability and maintenance efficiency of the overall system.

[0035] 3. In the present invention, by arranging an auxiliary maintenance mechanism, the storage plate can be rotated and opened while the push-pull frame is pulled open, providing the operator with a temporary work platform or storage area for convenient storage of tools and electrical components, ensuring that tools, equipment and components are always in an easy-to-access state during maintenance, without having to frequently leave the operating area to find tools. Tools or components can be placed directly on the open storage plate, avoiding unnecessary interference and interruption during the maintenance process, and greatly improving the efficiency of tool storage and retrieval during the maintenance process. It not only improves space utilization, simplifies the operating process, but also increases the cleanliness and safety of the work site. It is suitable for various maintenance work scenarios that require frequent use of tools and replacement of electrical components. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] A method for using a power high and low voltage switch cabinet comprises the following steps:

[0057] S1. When the high and low voltage switchgear cabinets need to be repaired on rainy days, the motor 401 is first used to drive the connected rotating plate 4 to rotate and stand up, which will drive the adjusting wheel 502 to rotate accordingly. At this time, the adjusting wheel 502 will mesh with the fixed annular rack 503, thereby driving the adjusting wheel 502 to rotate, so that the adjusting wheel 502 drives the worm 501 to rotate, so that the worm 501 drives the worm wheel 504 to rotate, so that the rotating shaft 505 connected to the worm wheel 504 rotates, thereby driving the rain shield 6 to rotate and block the front side of the switchgear cabinet 1;

[0058] S2. At the same time, when the rain shield 6 rotates, it will drive the transmission wheel 703 to rotate accordingly. When the transmission wheel 703 is meshed with the arc-shaped rack 704, it will drive the universal joint 702 connected to the transmission wheel 703 to rotate, so that the universal joint 702 drives the connected driving wheel 701 to rotate, so that the driving wheel 701 drives the two driven wheels 705 to rotate.

[0062] At the same time, when the rain shield 6 rotates, it will drive the transmission wheel 703 to rotate accordingly. When the transmission wheel 703 is meshed with the arc-shaped rack 704, the universal joint 702 connected to the transmission wheel 703 will be driven to rotate, so that the universal joint 702 drives the connected driving wheel 701 to rotate, so that the driving wheel 701 drives the two driven wheels 705 to rotate. At this time, the driven wheel 705 will drive the connected push-pull rod 706 to rotate, so that the push-pull rod 706 will drive the roller 707 to slide in the roller groove 803, thereby driving the moving frame 801 connected to the limit bar 802 to move, thereby driving the side baffle 804 to move out of the rain shield 6, and then when the adjusting gear 805 is meshed with the adjusting rack 602, it will drive the adjusting gear 805 to rotate, thereby driving the side baffle 804 connected to the adjusting gear 805 to rotate and keep in an inclined state, which is conducive to the flow of rainwater;

When the storage plate 1003 is completely moved out, the spring 1006 drives the connected retractable rack 1005 to move, thereby driving the storage plate 1003 connected to the retractable gear 1008 to rotate. With the opened elastic curtain 1004, a position for placing electrical components and tools can be formed, which is convenient for placing electrical components and tools during maintenance.

[0064] When the motor 401 needs to be repaired, the protective cover 403 is pulled up and rotated to remove the protective cover 403 so that the motor 401 can be repaired. After the repair is completed, the protective cover 403 is pulled up and rotated again, and under the action of the tension spring 404, the protective cover 403 is covered on the motor base 402 to protect the motor 401.
