Description

Technical Field

[0001] The utility model belongs to the technical field of switches, and in particular relates to a dual-power switching switch cabinet for an incoming line of a power distribution MCC section. Background Art

[0002] A dual power switch is a device used to switch between two power sources. Its main function is to automatically switch to the backup power supply in the event of a power failure to ensure continuous power supply to the receiving device. In the early days, dual power switches were composed of load isolation switches. Due to mechanical interlocking, high power consumption, and unreliable devices, they were used less and less in industry. With the continuous development of science and technology, an excitation dual power automatic transfer switch has emerged. In fact, it is a switch with relatively perfect working performance and high degree of automation. It is also equipped with an automatic controller with a single-chip microcomputer as the core and a control mechanism for electromechanical interlocking. It is a switch with perfect performance, safety and reliability.

[0003] The purpose of the excitation dual power automatic transfer switch is to ensure the continuity of power supply to important power load equipment so that it can play a good power supply role. Some equipment cannot be powered off, and many programs need to be restarted after power off. This is very time-consuming, and in such a large market environment, the excitation dual power automatic transfer switch has been widely used.

[0004] Since the excitation dual power automatic transfer switch is used as a power switch, in order to make it safer, thicker cables are used as circuit connection lines, and copper terminals are set at the ends of the cables to connect the transfer switch. The cables connect the upper and lower sides of the transfer switch to form a complete loop. The cables on the lower side of the transfer switch have better stability because the connection position is in the same direction as the gravity. However, when the cables on the upper side of the transfer switch are connected to the transfer switch, they need to be bent, and their thicker diameter leads to poor shaping ability. After the upper cables and the transfer switch are installed, they will generate a large pulling force due to their own gravity or the release of their own stress. Being in this environment for a long time may cause the copper terminals to be damaged or loose, thereby increasing the resistance at the connection between the cable and the transfer switch and the risk of circuit operation.

[0005] In order to solve the above problems, the present application proposes a power distribution MCC section incoming line dual power supply switching switch cabinet. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-3 , a power distribution MCC section incoming dual power supply switching switch cabinet, comprising a power distribution cabinet body 1, a switching switch body 20, a clamping plate 5, a positioning rod 8 and a clamping block 11, wherein the switching switch body 20 is arranged in the power distribution cabinet body 1;

[0027] The inner top wall of the power distribution cabinet body 1 is fixedly connected with a fixing frame 2, the inner side wall of the fixing frame 2 is fixedly connected with a spring 3, the top of the spring 3 is fixedly connected with a limit column 4, the bottom of the limit column 4 is fixedly connected with a clamping plate 5, the outer side wall of the limit column 4 is slidably connected to the inner side wall of the fixing frame 2, and an installation opening is opened on the clamping plate 5, the installation opening is used for the cable connected to the switching switch body 20 to pass through the clamping plate 5 through the installation opening, and is relatively fixed to the clamping plate 5, the bottom of the clamping plate 5 is fixedly connected with a connector 6, and the clamping plate 5 is fixedly connected with a connector 6. The holding plate 5 is rotatably connected to the connecting rod 7 through the connecting piece 6, and the end of the connecting rod 7 away from the connecting piece 6 is rotatably connected to the moving block 9. The inner wall of the power distribution cabinet body 1 is fixedly connected to the positioning rod 8, and the top of the moving block 9 is fixedly connected to the connecting plate 10. The outer wall of the connecting plate 10 is fixedly connected to the clamping block 11. The clamping block 11 is provided with an arc groove, which is used to hold one end of the cable connection switching switch body 20. When in use, the cable passes through the installation port provided on the clamping plate 5 and is relatively fixed to the clamping plate 5. After the cable is connected to the wiring terminal provided on the switching switch body 20, the clamping plate 5 will gradually slide toward the ground under the weight of the cable itself. During the sliding process of the clamping plate 5, the moving block 9 is pushed by the connecting rod 7 to gradually move in the direction close to the switching switch body 20. Since the top of the moving block 9 is provided with a connecting plate 10 and a clamping block 11, the moving block 9 will push the clamping block 11 to move in the direction of the cable during the movement. Since an arc groove is provided on the clamping block 11, the arc groove fits with the outer wall of the cable. When the clamping plate 5 moves toward the ground, it can push the clamping block 11 to move in the direction of the cable, thereby squeezing the cable, so that the cable and the wiring terminal on the switching switch body 20 are always in the same vertical line, thereby avoiding the cable and the wiring terminal being in a taut state for a long time, reducing the risk of separation or damage between the copper wiring terminal and the cable, increasing the service life of the equipment, and reducing the risk of circuit operation. The outer wall of the distribution cabinet body 1 is fixedly connected with a rain cover 24.

[0028] Reference Figure 4-5The inner bottom wall of the distribution cabinet body 1 is fixedly connected with a limit plate 12, and two limit plates 12 are provided. The two limit plates 12 are symmetrically distributed with respect to the central axis plane of the distribution cabinet body 1. The tops of the two limit plates 12 are provided with sliding grooves 13. The two limit plates 12 are slidably connected with a mounting frame 14 through the two sliding grooves 13. The outer side wall of the mounting frame 14 is fixedly connected with the outer side wall of the switching switch body 20, and the switching switch body 20 and the positioning rod 8 are respectively located on both sides of the mounting frame 14. The bottom of the mounting frame 14 is provided with a storage groove 15. There are two storage grooves 15, and the two storage grooves 15 are respectively located at the bottom of both sides of the mounting frame 14. The mounting frame 14 is fixedly connected with elastic pins 16 through the two storage grooves 15. The inner bottom wall of the distribution cabinet body 1 is fixedly connected with two arc blocks 17, and the two arc blocks 17 are respectively located in the distribution cabinet On both sides of the bottom of the main body 1, when there is no need to install or repair the switch main body 20, the mounting frame 14 can be pushed so that the elastic pin 16 set at the bottom of the mounting frame 14 is engaged with the arc block 17 set at the bottom of the distribution cabinet main body 1. Since the top of the arc block 17 is set to an arc shape, when the mounting frame 14 is not pulled by external force, the elastic pin 16 is at the top center of the arc block 17, thereby limiting the position of the mounting frame 14. When maintenance and installation are required, the mounting frame 14 can be pulled. At this time, the bottom of the elastic pin 16 gradually fits with the top of the arc block 17. Under the action of the outer wall of the arc block 17, the elastic pin 16 is forced to shrink to the inside of the storage groove 15, thereby releasing the restriction of the arc block 17 on the mounting frame 14, making it convenient for the staff to pull the mounting frame 14 to the door of the distribution cabinet main body 1, which is convenient for the staff to repair.

[0029] Reference Figure 2 and Figure 4 A handle 18 is fixedly connected to the outer wall of the mounting frame 14, and an anti-sliding block 26 is fixedly connected to the top of the handle 18. The handle 18 is located at the top of the mounting frame 14, and the material of the handle 18 is rubber, which is convenient for the staff to adjust the position of the mounting frame 14 through the handle 18. Because the material of the handle 18 is rubber, the risk of electric shock to the staff when adjusting the position of the mounting frame 14 is greatly reduced, and a plurality of anti-sliding blocks 26 are arranged on the top of the handle 18 to prevent the staff from slipping out of the handle 18 when pulling it.

[0030] Reference Figure 1A blocking plate 19 is fixedly connected to the inner wall of the distribution cabinet body 1, and the blocking plate 19 is slidably connected to the inner surface of the mounting frame 14 on the side close to the distribution cabinet body 1. Four blocking plates 19 are provided, and the four blocking plates 19 are divided into two groups. The two groups of blocking plates 19 are respectively located on the inner wall of the distribution cabinet body 1, and the two groups of blocking plates 19 are symmetrically distributed on the central axis plane of the distribution cabinet body 1. The outer walls of the four blocking plates 19 are slidably connected to the inner surface of the mounting frame 14 to prevent the angle between the mounting frame 14 and the distribution cabinet body 1 from changing when the mounting frame 14 moves, thereby preventing the mounting frame 14 from tipping over when moving.

[0031] Reference Figure 1 A vent 21 is provided through the outer wall of the power distribution cabinet body 1, and a rain cover 24 is located on the outer side of the vent to shield the vent 21. Two vents 21 are provided, and the two vents 21 are respectively located on the outer walls of the two sides of the power distribution cabinet body 1. The number of positions of the rain cover 24 corresponds to the number of positions of the vent 21. When the equipment is used for a long time, the internal temperature of the power distribution cabinet body 1 gradually increases. The two vents 21 are used to increase the circulation speed of the air inside the power distribution cabinet body 1 and the air outside the power distribution cabinet body 1, thereby improving the heat dissipation efficiency inside the power distribution cabinet body 1, avoiding excessive temperature inside the power distribution cabinet body 1, thereby avoiding damage to the electrical components inside the power distribution cabinet body 1, and greatly reducing the risk of rainwater entering the power distribution cabinet body 1 in bad weather such as wind and rain through the two rain covers 24, thereby improving the safety of the electrical components inside the power distribution cabinet body 1.

[0032] Reference Figure 1 and Figure 5 A pulley 22 is provided at the bottom of the distribution cabinet body 1, and a placement groove 27 is opened at the bottom of the distribution cabinet body 1. The placement groove 27 is located on the outside of the pulley 22 to store the pulley 22. Four pulleys 22 are provided, and the four pulleys 22 are respectively located at the four corners of the bottom of the distribution cabinet body 1. The position of the placement groove 27 corresponds to the position of the four pulleys 22, which is convenient for the staff to adjust the position of the distribution cabinet body 1 and reduce the labor intensity of the staff. After the staff adjusts the position of the distribution cabinet body 1, the four pulleys 22 are retracted into the four placement grooves 27 to avoid the position of the distribution cabinet body 1 from shifting during use.

[0033] Reference Figure 2 A wiring opening 23 is provided on the outer wall of the power distribution cabinet body 1, and a rubber strip 25 is covered on the inner wall of the wiring opening 23 to protect the outer sheath of the cable. The wiring opening 23 is located at the top of one side of the power distribution cabinet body 1 close to the clamping plate 5. The rubber strip 25 is located between the cable and the power distribution cabinet body 1, which is convenient for wiring after the cable is installed and avoids excessive bending of the cable due to wiring problems. At the same time, the rubber strip 25 avoids friction between the cable and the cross-section of the outer wall of the power distribution cabinet body 1, thereby avoiding damage to the cable.

[0034] Working principle: When in use, the cable passes through the installation opening provided on the clamping plate 5 and is relatively fixed to the clamping plate 5. After the cable is connected to the wiring terminal provided on the switching switch body 20, the clamping plate 5 will gradually slide toward the ground under the weight of the cable itself. During the sliding process of the clamping plate 5, the moving block 9 is pushed by the connecting rod 7 to gradually move toward the direction close to the switching switch body 20. Since a connecting plate 10 and a clamping block 11 are provided on the top of the moving block 9, the moving block 9 will push the clamping block 11 to move toward the direction of the cable during the movement. Since an arc groove is provided on the clamping block 11, the arc groove fits with the outer wall of the cable. When the clamping plate 5 moves toward the ground, it can push the clamping block 11 to move toward the direction of the cable, thereby squeezing the cable, so that the cable and the wiring terminal on the switching switch body 20 are always in the same vertical line, thereby avoiding the cable and the wiring terminal from being in a taut state for a long time, reducing the risk of separation or damage between the copper wiring terminal and the cable, improving the service life of the equipment, and reducing the risk of circuit operation.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
