Description

Technical Field

[0001] The utility model relates to the technical field of isolating switches, in particular to an isolating switch suitable for use in a coastal severe corrosion environment. Background Art

[0002] The severe corrosion environment along the coast usually refers to salt fog, which refers to a dispersion system composed of tiny salt droplets in the atmosphere. Salt fog is mainly caused by the violent disturbance of seawater in the ocean, the breaking of wind and waves, and the waves hitting the shore, which produce a large amount of foam and bubbles. When the bubbles burst, tiny water droplets are generated, some of which are in a state of equilibrium with eddy diffusion and are distributed on the sea surface. They rise into the air with the air flow, and evolve into a dispersion system through processes such as cracking, evaporation, and mixing, forming an atmospheric salt nucleus. In the process of using electricity in coastal areas, isolating switches are needed. Isolating switches are a type of switching device that is mainly used for "isolating power supplies, switching operations, and connecting and disconnecting small current circuits" without arc extinguishing function. Existing isolating switches still have certain defects when used.

[0003] The working principle and structure of the isolating switch in the prior art are relatively simple. The main feature of the isolating switch is that it has no arc extinguishing ability and can only open and close the circuit when there is no load current. It can be opened and closed as needed. Usually, the isolating switch can be installed at a specified height through a base. The isolating switch is usually fixed to the base with bolts, and the mounting hole on the base is large, so the installation operation is more troublesome. When personnel install at high altitude, it is easy to cause collision and damage to parts such as insulators, thereby affecting the subsequent use of the isolating switch. Utility Model Content

[0004] The utility model aims to provide a disconnector suitable for use in a coastal severe corrosion environment, so as to solve the problem of troublesome installation and fixation between the insulator and the base on the disconnector currently on the market, as mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disconnector suitable for use in a coastal severe corrosion environment, comprising: a first base, a second base, an insulator, a static contact seat, a knife switch, a moving contact seat and a positioning groove, a second base is arranged on the outer side of the first base, insulators are installed above the first base and the second base, a static contact seat is installed on the upper side of the insulator close to the first base, a knife switch is connected to the inside of the static contact seat through a fastener, the end of the knife switch is connected to the moving contact seat through a fastener, the bottom of the moving contact seat is connected to the end of the insulator close to the second base, the positioning grooves are all opened through the inside of the first base and the second base, the bottom surfaces of the first base and the second base are welded with connecting blocks, the bottom of the insulator is respectively installed with a positioning block and a plug-in block, a stainless steel spring is connected to the inside of the plug-in block, a clamping block is connected to one end of the stainless steel spring, and a limiting block is welded on the outside of the clamping block.

[0006] Preferably, the material of the stationary contact seat and the moving contact seat is graphene material.

[0007] Preferably, a sliding structure is formed between the clamping block and the connecting block through a stainless steel spring, and two groups of clamping blocks are arranged about the center of the plug-in block.

[0008] Preferably, a fixing block is provided at the bottom of the first base and the bottom of the second base.

[0009] Preferably, a T-shaped slot is provided inside the fixing block, a T-shaped block is connected inside the T-shaped slot, and the top of the T-shaped block is connected to the bottom of the first base and the second base.

[0010] Preferably, a sliding rod is welded at the bottom of the T-block, a threaded collar is connected to the end of the sliding rod, and the end of the sliding rod is threaded.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model is suitable for isolating switches in coastal heavily corrosive environments; when the card block is squeezed, the stainless steel spring can be compressed, and when the card block moves, the limit block can be driven to move; when the card block completely slides into the plug-in block, the insulator can be pushed to move, and the threaded collar can squeeze and fix the fixed block, thereby eliminating the need to punch holes on the base again, making it convenient for isolating switches of different models to adjust the position of the base during installation so that the switch can be closed.

[0012] 1. The isolating switch is mainly used to reliably isolate the part of the high-voltage power distribution device that needs to be shut down from the live part. Usually, the isolating switch connection base is installed at a designated high-altitude position, and the traditional installation and fixing method between the insulator and the base is relatively cumbersome. When the card block is squeezed, the stainless steel spring can be compressed, and the card block can drive the limit block to move when it moves. When the card block slides completely into the plug-in block, the insulator can be pushed to move, and when the insulator moves, the plug-in block can be driven to move. When the bottom of the insulator moves to the surface above the first base and the second base, the plug-in block can pass through it. When the two groups of card blocks pass through the first base and the second base, the positioning block can be plugged into the positioning groove. At the same time, the two groups of card blocks can be reset by the stainless steel spring. At this time, the insulator can be quickly installed above the first base and the second base, and the installation process is relatively stable, which is convenient for the isolating switch to simply and conveniently install the insulator on the base during use.

[0013] 2. The length of the switch blade varies depending on the type of disconnector. Usually, the length of the base is fixed, and the position of the fixing hole is pre-opened, which makes it difficult for the base to be suitable for the installation of disconnectors of different types. When the second base moves, it can drive the T-block to move, and the T-block can slide through the T-slot when it moves, and the sliding rod can be driven to move when the T-block slides. When the second base moves to the specified position, the threaded ring can be rotated when the switch blade is closed, and the threaded ring can slide when it rotates, and the threaded ring can squeeze and fix the fixed block, so there is no need to punch holes on the base again, which is convenient for different types of disconnectors to adjust the position of the base during installation so that the switch blade can be closed.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the utility model provides a technical solution: a disconnector suitable for use in a coastal heavily corrosive environment, comprising: a first base 1, a second base 2, an insulator 3, a static contact seat 4, a knife switch 5, a moving contact seat 6 and a positioning groove 7, the second base 2 is arranged on the outside of the first base 1, the insulator 3 is installed above the first base 1 and the second base 2, the static contact seat 4 is installed on the side of the insulator 3 close to the first base 1, the inside of the static contact seat 4 is connected with a knife switch 5 through a fastener, the end of the knife switch 5 is connected with the moving contact seat 6 through a fastener, and the bottom of the moving contact seat 6 is connected to the side close to the second base 2 On the end of the insulator 3, the positioning grooves 7 are all opened through the inside of the first base 1 and the second base 2. The bottom surfaces of the first base 1 and the second base 2 are welded with connecting blocks 8. The bottom of the insulator 3 is respectively installed with a positioning block 9 and a plug-in block 10. The plug-in block 10 is connected to a stainless steel spring 11. One end of the stainless steel spring 11 is connected to a clamping block 12. A limiting block 13 is welded to the outside of the clamping block 12. The material of the static contact seat 4 and the moving contact seat 6 is graphene material. The stainless steel spring 11 forms a sliding structure between the clamping block 12 and the connecting block 8, and two groups of clamping blocks 12 are arranged about the center of the plug-in block 10.

[0022] In specific implementation, the isolating switch is mainly used to reliably isolate the part of the high-voltage power distribution device that needs to be powered off from the live part to ensure the safety of maintenance work. Usually, the isolating switch connection base is installed at a designated high altitude position, and the traditional installation and fixing method between the insulator 3 and the base is relatively cumbersome. For this reason, the two sets of card blocks 12 can be pressed. When the card block 12 is squeezed, the stainless steel spring 11 can be compressed, and when the card block 12 moves, the limit block 13 can be driven to move. When the limit block 13 moves, it can slide through the plug-in block 10. When the card block 12 completely slides into the plug-in block 10, When the insulator 3 is moved to the upper surface of the first base 1 and the second base 2, the plug-in block 10 can pass through the inside thereof. When the two groups of card blocks 12 pass through the inside of the first base 1 and the second base 2, the positioning block 9 can be plugged into the inside of the positioning groove 7. At the same time, the two groups of card blocks 12 can be reset by the stainless steel spring 11. When the card blocks 12 are reset, they can pass through the plug-in block 10. At this time, the insulator 3 can be quickly installed above the first base 1 and the second base 2, and the installation process is relatively stable.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the insulator 3 can be simply and conveniently installed on the base during use of the isolating switch.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 It can be seen that a fixed block 14 is commonly provided at the bottom of the first base 1 and the second base 2, a T-slot 15 is provided inside the fixed block 14, a T-slot 15 is connected to a T-block 16 inside the T-slot 15, the top of the T-block 16 is connected to the bottom of the first base 1 and the second base 2, a sliding rod 17 is welded to the bottom of the T-block 16, a threaded collar 18 is connected to the end of the sliding rod 17, the end of the sliding rod 17 is threaded, and a sliding structure is formed between the T-block 16 and the fixed block 14 through the T-slot 15.

[0025] During specific implementation, the lengths of the blades 5 of the isolating switches are different for different models. The two groups of insulators 3 need to be installed on the fixing holes of the base according to the closing position of the blades 5. Usually, the length of the base is fixed, and the position of the fixing holes is pre-opened, which makes it difficult for the base to be suitable for the installation of isolating switches of different models. At this time, the second base 2 can be pulled to move, and the second base 2 can drive the T-block 16 to move when it moves. The T-block 16 can slide through the T-slot 15 when it moves, and the T-block 16 can drive the slide bar 17 to move when it slides. When the slide bar 17 moves, it can drive the threaded collar 18 to move. When the second base 2 moves to the specified position, the blade 5 can be closed, and the threaded collar 18 can be rotated. When the threaded collar 18 rotates, it can slide threadably, and the threaded collar 18 can squeeze and fix the fixing block 14, so there is no need to punch holes on the base again.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 It can be seen that during the installation process of isolating switches of different models, the position of the base can be adjusted so that the switch 5 can be closed.

[0027] To sum up, when using the isolating switch suitable for coastal severe corrosion environment, the connection or disconnection of the electric transmission closing contacts is realized by mechanical transmission. When the switch is in the open state, the controlled amount of electricity will not flow through. Even if the power supply next to the switch is turned on, the circuit breaker can maintain a normal working state. The isolating switch is a prior art and will not be described in detail here. The insulator 3 can be installed on the base in a simple and convenient way, and it is not easy to cause damage to the parts. By adjusting the distance between the first base 1 and the second base 2, different types of isolating switches can be closed. In the utility model, the improvement of the isolating switch belongs to the structural improvement. Therefore, this improved isolating switch is not only suitable for coastal severe corrosion environment, but also suitable for other similar mountain humid environments using isolating switches. It has good versatility. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
