[0002] The trolley - type high - voltage cabinet is a kind of high - voltage switchgear, in which main equipment such as circuit breakers is installed on a retractable trolley, which is convenient for maintenance and replacement. The original design intention of the trolley - type high - voltage cabinet is to ensure the safety of operators and the convenience of equipment maintenance. On the premise of switch disconnection, the trolley can be pulled out from the switch cabinet along the guide rail for maintenance or replacement, which greatly improves work efficiency and safety.

[0003] When the existing trolley - type high - voltage cabinet is in use, only the rollers arranged at its bottom play a role in support and movement. After frequent rolling, the rollers will be worn to a certain extent, which will cause the trolley to be unstable during movement, resulting in an unstable connection between the disconnector and the corresponding static contact; the wear of the rollers also causes the trolley to sink downward by a small distance, so that the disconnector at the upper end of the trolley and the corresponding static contact drop by a small distance, which may lead to a loose connection between the upper disconnector and the corresponding static contact, thus increasing the temperature at the connection between the two and increasing power consumption. Summary of the Utility Model

[0004] Aiming at the problem in the prior art that the connection between the disconnector and the corresponding static contact is unstable due to roller wear, increasing power consumption, the utility model proposes the following technical solutions:

[0030] Embodiment

[0031] As Figures 1-3As shown in the figure, a one-key sequence control compact intelligent high-voltage switchgear includes a cabinet body 1, and a circuit breaker unit 5 is movably installed in the cabinet body 1. The circuit breaker unit 5 includes a trolley frame 51. The high-voltage switchgear further includes:

[0032] A bottom rail 41 and a middle rail 42 fixedly installed in the cabinet body 1;

[0033] Bottom rollers 55. A bottom frame 52 is fixedly installed on the trolley frame 51, and a plurality of bottom rollers 55 are installed at the bottom of the bottom frame 52. When the trolley frame 51 is moved, the bottom rollers 55 roll on the bottom rail 41;

[0034] Side rollers 56. A middle frame 53 is fixedly installed on the trolley frame 51, and a plurality of side rollers 56 are installed on the side of the middle frame 53. When the trolley frame 51 is moved, the side rollers 56 roll on the middle rail 42.

[0035] In actual application of this embodiment, the trolley frame 51 uses a plurality of bottom rollers 55 and a plurality of side rollers 56 to support and move the entire circuit breaker unit 5, thereby improving the stability of the trolley frame 51 and the stability of the connection between the disconnector 54 and the corresponding static contact; when the bottom rollers 55 are worn, there are still side rollers 56 for support and movement, which is not easy to cause the connection between the upper disconnector 54 and the corresponding static contact in the cabinet body 1 to be loose, effectively avoiding the temperature rise at the connection between the disconnector 54 and the static contact, thereby reducing the power consumption.

[0036] Further, bridge-shaped rollers 57 are installed on the side of the trolley frame 51. When the trolley frame 51 is moved, the bridge-shaped rollers 57 roll on the inner wall of the cabinet body 1.

[0037] In actual application of this embodiment, the bridge-shaped rollers 57 limit the positions of a plurality of bottom rollers 55 and a plurality of side rollers 56, effectively avoiding the bottom rollers 55 or the side rollers 56 from deviating from the track, improving the stability of the trolley frame 51, the stability of the connection between the disconnector 54 and the corresponding static contact, and thereby reducing the power consumption.

[0038] Further, the bottom rollers 55 and the side rollers 56 are in a vertical state, and the bridge-shaped rollers 57 are in a horizontal state.

[0039] In actual application of this embodiment, the bridge-shaped rollers 57 on both sides of the trolley frame 51 are in contact with the two inner walls in the cabinet body 1, so that the trolley frame 51 is located in the middle position in the cabinet body 1, and at the same time, the trolley frame 51 is kept in a straight line during the movement process, thereby improving the stability of the trolley frame 51, the stability of the connection between the disconnector 54 and the corresponding static contact, and thereby reducing the power consumption.

[0040] Such as Figure 1As shown in the figure, the cabinet body 1 is divided into several compartments according to units, namely the instrument installation compartment 2, the busbar installation compartment 3, the circuit breaker unit installation compartment 4, and the incoming and outgoing line cable installation compartment 6.

[0041] Among them, the circuit breaker unit 5 is located in the circuit breaker unit installation compartment 4.

[0042] In actual application of this embodiment, several compartments are respectively arranged in the cabinet body 1, and the corresponding equipment is effectively distributed through the corresponding compartments, making the structure inside the entire cabinet body 1 relatively compact and reducing the volume of the cabinet body 1.

[0043] As Figures 3-5 shown, a plurality of disconnectors 54 are installed on the trolley frame 51 through the isolation shaft 7. An energy storage component 8 and a control component 9 are installed inside the trolley frame 51. The trolley frame 51 is provided with a first panel 511 and a second panel 512. The isolation shaft 7 respectively penetrates through the first panel 511 and the second panel 512. The energy storage component 8 is installed between the first panel 511 and the second panel 512, and the control component 9 is installed outside the second panel 512.

[0044] In actual application of this embodiment, the energy storage component 8 is used to improve the speed of opening and closing the disconnector 54, thereby improving the safety during operation; the control component 9 can accurately control the servo motor corresponding to the isolation shaft 7 to stop running, so that the position of the isolation shaft 7 when it stops rotating is relatively accurate.

[0045] Further, the energy storage component 8 includes a transmission frame 81 and an energy storage member 82. The transmission frame 81 is fixedly installed around the isolation shaft 7. One end of the energy storage member 82 is movably installed on the first panel 511, and the other end is movably installed on the transmission frame 81.

[0046] In actual application of this embodiment, when the isolation shaft 7 rotates, it will drive the transmission frame 81, and the transmission frame 81 squeezes the energy storage member 82 to store energy. When the isolation shaft 7 rotates to a certain extent, the energy storage member 82 releases energy to make the isolation shaft 7 quickly rotate to the specified position, thereby improving the speed of opening and closing the disconnector 54.

[0047] Further, the control component 9 includes a cam 91 and a microswitch 92. The cam 91 is fixedly installed around the isolation shaft 7, and the microswitch 92 is installed on the second panel 512. When the isolation shaft 7 rotates, the cam 91 rotates around the isolation shaft 7 and touches the microswitch 92.

[0048] In actual application of this embodiment, when the isolation shaft 7 rotates, it will drive the cam 91 to rotate. When the cam 91 touches the microswitch 92 during the transmission process, the microswitch 92 will control the servo motor to stop running, so that the position of the isolation shaft 7 when it stops rotating is relatively accurate.

[0049] Working principle: When moving the trolley rack 51, the bottom rollers 55 roll on the bottom rail 41, the side rollers 56 roll on the middle rail 42, and the bridge-shaped rollers 57 roll on the inner wall of the cabinet body 1, improving the overall stability of the trolley rack 51, effectively avoiding the increase in temperature at the connection between the disconnector 54 and the static contact, thereby reducing the power consumption; several compartments are arranged in the cabinet body 1, making the structure inside the entire cabinet body 1 relatively compact and reducing the volume of the cabinet body 1; the energy storage component 8 improves the speed of the disconnector 54 during opening and closing, thereby improving the safety during operation; through the control component 9, the servo motor corresponding to the isolation shaft 7 can be accurately controlled to stop running, so that the position of the isolation shaft 7 when it stops rotating is relatively accurate.

[0050] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
