Description

Technical Field

[0001] The invention relates to the technical field of GIS equipment, and in particular to a dustproof chamber for installing a GIS branch busbar. Background Art

[0002] Gas-insulated metal-enclosed switchgear is a metal-enclosed switchgear and control equipment that uses gas pressure higher than atmospheric pressure as the insulating medium at least in part, hereinafter referred to as GIS. It assembles all kinds of electrical equipment in the substation except the transformer, including circuit breakers, disconnectors, grounding switches, voltage transformers, current transformers, busbars, etc. in a metal casing, and fills it with 0.4-0.5Mpa SF6 gas to achieve reliable insulation of high-voltage conductors to the casing, between phases and between breaks. Due to its advantages of small footprint, compact structure and reliable operation, it has become one of the important components of substations.

[0003] However, the reliable operation of GIS equipment is inseparable from a highly clean installation and docking environment. If dust particles enter or remain in the GIS equipment during the installation and docking of GIS equipment, it is easy to cause GIS equipment to leak, discharge and other faults, thus leaving safety hazards for the normal operation of the substation. Therefore, at the construction site of GIS equipment installation and maintenance, a mobile dustproof room is usually built to protect the installation and maintenance of GIS equipment from dust and moisture.

[0004] In the prior art, when installing a GIS branch busbar at a high place, a support frame and an inflatable dustproof shed are used. An operating platform is provided on the top of the support frame, and an inflatable dustproof shed, i.e., a dustproof room, is provided on the operating platform. The side wall of the inflatable dustproof shed has an escape opening for the cylinder of the GIS equipment to pass through. After the operator changes the operating clothes on site, he climbs up the support frame and enters the inflatable dustproof shed to operate. After changing the operating clothes on site, since the site cannot be guaranteed to be a dust-free environment, the operating clothes will inevitably be stained with dust. Climbing from the ground through the support frame to the opening of the dustproof room, entering the dustproof room for operation will bring in some dust, and the dust brought into the dustproof room will still cause the GIS equipment to malfunction during use. Summary of the invention

[0005] The purpose of the present invention is to provide a dustproof room for installing a GIS branch busbar, which is used to solve the problem that when installing a GIS branch busbar at a high place in the dustproof room in the prior art, after changing the operating clothes on site, since the site cannot be guaranteed to be a dust-free environment, the operating clothes will inevitably be stained with dust, and climbing from the ground through the support frame to the opening of the dustproof room and entering the dustproof room for operation will bring in some dust, and the dust brought into the dustproof room will still cause malfunctions of the GIS equipment during use.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions.

[0008] Furthermore, the interlayer floor includes a horizontal bottom plate and a restraining vertical edge arranged at the edge of the horizontal bottom plate. The inflatable dustproof shed inside the upper frame is placed on the horizontal bottom plate and the bottom of its side wall is limited in the horizontal direction by the corresponding restraining vertical edge.

[0009] Furthermore, the outside of the avoidance is connected to a cylindrical dust curtain which is sleeved on the cylinder of the GIS equipment.

[0010] Furthermore, a ladder is provided in the lower support frame to facilitate operators to go up and down.

[0011] Furthermore, the isolation door is a flip door, and the rotation axis of the flip door is parallel to the axis of the busbar.

When using the dustproof room for installing the GIS branch busbar of the present invention to install the GIS branch busbar at a high place, the operator can first enter the transition room inside the lower support frame to change the operating clothes, and then pass through the isolation door to enter the dustproof room in the upper frame, which can further prevent dust from entering the dustproof room, ensure that no dust enters or remains in the GIS equipment when installing the GIS branch busbar, and prevent the GIS equipment from malfunctioning during use.

[0024] Based on the above concept, the present invention provides a variety of different embodiments of dustproof chambers for GIS branch bus installation for illustration.

[0025] In a basic embodiment, Figure 1 , 2 As shown, the dustproof room for installing the GIS branch busbar of the present invention includes a frame, which includes a lower support frame 8 and an upper frame 1. An interlayer floor 2 is provided between the lower support frame 8 and the upper frame 1. An isolation door 3 is provided on the interlayer floor 2 for operators to pass through the upper and lower layers. Each side of the lower support frame 8 is provided with a shielding curtain that encloses the interior of the lower support frame to form a transition room 9. An inflatable dustproof shed is provided inside the upper frame 1 to form a dustproof room 10. The side wall of the inflatable dustproof shed inside the upper frame is provided with an escape opening for the cylinder of the GIS equipment to pass horizontally. The operator can change the operating clothes in the lower transition room 9, and then enter the upper dustproof room 10 through the isolation door 3 provided on the interlayer floor 2 to operate, further preventing dust from entering the dustproof room 10, ensuring that no dust enters or remains in the GIS equipment when installing the GIS branch busbar, and preventing the GIS equipment from malfunctioning during use.

[0026] Based on the above embodiment, the interlayer floor 2 may be only a horizontal bottom plate 21, and the inflatable dustproof shed is placed on the horizontal bottom plate 21. In a preferred embodiment, as Figure 1 As shown, the interlayer floor 2 includes a horizontal bottom plate 21 and a restraining edge 22 arranged on the edge of the horizontal bottom plate 21. The inflatable dustproof shed is placed on the horizontal bottom plate 21 and the bottom of the side wall is limited in the horizontal direction by the corresponding restraining edge 22, thereby improving the stability of the inflatable dustproof shed in the upper frame 1 when using the dustproof room for installing the GIS branch busbar of the present invention.

[0027] On the basis of the above embodiment, the side wall of the inflatable dustproof shed in the upper frame 1 is provided with a relief opening for the GIS equipment cylinder to pass horizontally, and the GIS equipment passes into the dustproof room 10 to install the branch busbar. In a preferred embodiment, Figure 2-3 As shown, the outer side of the avoidance opening is also connected to a cylindrical dust curtain 13 which is sleeved on the GIS equipment, so as to further prevent external dust from entering the dustproof chamber 10.

[0028] On the basis of the above embodiment, the operator enters the dustproof room 10 in the upper frame 1 from the transition room 9 in the lower support frame 8 through the support frame body of the lower support frame 8 to perform the operation. Figure 1-2 As shown, a ladder 4 is provided in the lower support frame 8 for the operator to go up and down. This makes it convenient for the operator to travel back and forth between the upper frame 1 and the lower support frame 8, and also makes it safer for the operator to enter the dustproof room 10 in the upper frame 1 or come out of the dustproof room 10 after the operation is completed.

[0029] On the basis of the above embodiment, the isolation door 3 provided on the interlayer floor 2 can be removed from the interlayer floor 2 as a whole, so that the operator can enter the dustproof room 10 in the upper frame 1. In a preferred embodiment, as Figure 1 As shown, the isolation door 3 arranged on the interlayer floor 2 is a flip door, and the rotating shaft of the flip door is parallel to the axis of the busbar, so that the space in the dustproof room 10 can be utilized to a greater extent.

[0030] On the basis of the above embodiment, the lower support frame 8 can be set as an integral non-liftable support frame. In a preferred embodiment, the lower support frame 8 is set as a liftable support frame, which can adapt to the installation of GIS equipment of different heights.

[0031] On the basis of the above embodiment, the upper frame 1 and the lower support frame 8 of the frame body are an integral frame body. In a preferred embodiment, as Figure 1 As shown, the lower support frame 8 is a scaffold-type liftable support frame, and the upper frame 1 can also be a scaffold-type frame. The upper frame 1 includes a plurality of upper cross bars 11 and a plurality of upper vertical bars 12, and the upper frame 1 as a whole can be removed from the lower support frame 8. Preferably, there are 6 upper cross bars 11 and 4 upper vertical bars 12. In this way, the overall structure of the upper frame 1 is relatively simple, and rapid installation and removal can also be achieved, which improves the efficiency of GIS equipment installation as a whole.

[0032] Based on the above embodiment, the frame relies on each column to stabilize the operating platform. In a preferred embodiment, Figure 1-2As shown, the outer side of each column of the frame is connected with a diagonal brace 6, the upper end of the diagonal brace 6 is connected to the position of the column corresponding to the interlayer floor 2, and a reinforcing brace 7 for connecting the frame column and the diagonal brace 6 is also provided on the diagonal brace 6, so that the frame is more stable and the safety is improved.

[0033] On the basis of the above embodiment, when the GIS branch busbar is installed or needs to enter the next station, the upper frame 1 can be removed and the lower support frame 8 can be moved away or moved to the next station as a whole. Figure 1 As shown, the bottom end of each column of the frame is provided with a universal wheel 5 which can drive the frame to move, so that the movement of the frame is more convenient and the efficiency of the GIS branch busbar installation is improved.

[0034] When using the dustproof room for installing the GIS branch busbar of the present invention, first adjust the lower support frame 8 to an appropriate height, and after installing the interlayer floor 2 and the upper frame 1, the isolation door 3 arranged on the interlayer floor 2 is a flip door, and the rotating shaft of the flip door is parallel to the axis of the busbar, and each side of the lower support frame 8 is equipped with a shielding curtain that encloses the interior of the lower support frame 8 to form a transition room 9, and the upper frame 1 is equipped with an inflatable dustproof shed to form a dustproof room 10. The operator enters the transition room 9 in the lower support frame 8 to change the operating clothes, and then enters the inflatable dustproof shed, i.e., the dustproof room 10 in the upper frame 1 through the isolation door 3 by the ladder 4 to operate, which can further prevent dust from entering the dustproof room 10, ensuring that no dust enters or remains in the GIS equipment when installing the GIS branch busbar, thereby preventing the GIS equipment from malfunctioning during use.
