Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of outdoor SVG, and in particular relates to an integrated SVG bypass switch. Background Art
[0002] Outdoor SVG devices are connected via AC-core stranded conductors (AC-SSC), requiring ample clearance for maintenance. Current transformers, lightning arresters, arrester counters, and GW5 bypass disconnectors are typically installed as separate devices and secured to other equipment via AC-core stranded conductors. This occupies a large area and incurs high material costs. Furthermore, the arrester should not be subjected to excessive stress, as the tension generated by the AC-core stranded conductors securing it in strong winds can damage it. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to provide an integrated SVG bypass switch. The utility model integrates a current transformer, a lightning arrester and a lightning arrester counter, and a GW5 type bypass disconnector into a whole through a steel bracket, channel steel, and a mounting plate, thereby reducing the footprint of the SVG equipment and lowering the equipment material cost and installation cost.
[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0005] An integrated SVG bypass switch includes a bracket, a top cross support is installed on the top of the bracket, an "L"-shaped mounting plate, a current transformer and a lightning arrester are installed on the top cross support, and a lightning arrester counter is provided on the "L"-shaped mounting plate; a side bracket is installed on the side of the bracket, and a bypass isolation switch is installed on the side bracket.
[0006] Preferably, the bracket includes a left steel bracket and a right steel bracket, and the top cross support is a steel bracket top channel steel;
[0007] The steel bracket top channel steel is fixed on the top of the left steel bracket and the top of the right steel bracket.
[0008] Preferably, the side bracket is a steel bracket side channel steel, and the steel bracket side channel steel is fixed on the same side of the left steel bracket and the right steel bracket.
[0009] Preferably, the "L"-shaped mounting plate is fixed to the top channel steel of the steel bracket.
[0010] Preferably, the side bracket is a steel bracket side channel steel, the bypass disconnector is a GW5 type bypass disconnector, and the GW5 type bypass disconnector is fixed on the steel bracket side channel steel.
[0011] Preferably, the current transformer and lightning arrester are fixed on the top channel steel of the steel support.
[0012] Preferably, the arrester counter is fixed on an "L"-shaped mounting plate.
[0013] Preferably, the switch further comprises an electric mechanism bracket, and the electric mechanism bracket is fixed on the left steel bracket.
[0014] Preferably, the switch further comprises an electric mechanism, and the electric mechanism is fixed on the electric mechanism bracket.
[0015] The utility model can achieve the following beneficial effects:
[0016] This utility model integrates a current transformer, a lightning arrester, a lightning arrester counter, and a GW5 bypass disconnector into a single unit using a steel bracket, channel steel, and mounting plate. This reduces the SVG equipment footprint and reduces both material and installation costs. The L-shaped mounting plate facilitates ground-level observation of the lightning arrester counter. When connecting this integrated SVG to other SVG equipment via steel-core aluminum stranded wire, connections only need to be made at the ends of the current transformer. The lightning arrester is connected to the current transformer via tinned soft copper wire, reducing stress on the arrester and extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The preferred solution is Figures 1 to 2 As shown, an integrated SVG bypass switch includes a left steel support 1, a right steel support 2, a steel support top channel steel 3, a steel support side channel steel 4, an "L"-shaped mounting plate 5, a GW5 type bypass disconnector 6, a current transformer 7, a lightning arrester 8, a lightning arrester counter 9, a motor-driven mechanism 10 and a motor-driven mechanism support 11.
[0022] The top channel steel 3 of the steel bracket is installed on the top of the left steel bracket 1 and the right steel bracket 2, and is connected by bolts. The height of the left steel bracket 1 and the right steel bracket 2 remains consistent.
[0023] The steel bracket side channel steel 4 is welded to the same side of the left steel bracket 1 and the right steel bracket 2. In order to prevent the connection from being unstable under strong wind conditions on site and causing the connection to break over time, full welding is required.
[0024] The "L"-shaped mounting plate 5 is mounted on the top channel steel 3 of the steel bracket by means of bolts.
[0025] The GW5 type bypass disconnector 6 is mounted on the side channel steel 4 of the steel bracket by means of bolts.

Figure 2 When the integrated SVG device shown is connected to other SVG devices, cables are connected through the terminal blocks on both sides of the top of the current transformer 7. Tinned soft copper wire is used to connect the lightning arrester 8 and the current transformer 7, which reduces the stress on the lightning arrester and extends its service life.
[0027] The arrester counter 9 is mounted on an L-shaped mounting plate 5 by means of bolts. The L-shaped mounting plate 5 has a certain angle, which makes it convenient for on-site personnel to observe the count value of the arrester counter 9 from the ground.
[0028] The electric mechanism bracket 11 is welded to the left steel bracket 1 and needs to be fully welded.
[0029] The electric mechanism 10 is mounted on the electric mechanism bracket 11 by means of bolts.
