Description

Technical Field

[0001] The present invention relates to the technical field of isolating switch production, in particular to a production process of isolating switches. Background Art

[0002] An isolating switch is a switching device that is primarily used for "isolating power sources, switching operations, and connecting and disconnecting low-current circuits" and does not have an arc extinguishing function. When the isolating switch is in the open position, the contacts have an insulation distance that meets the specified requirements and a clear disconnect mark; when in the closed position, it is a switching device that can carry the current under normal circuit conditions and the current under abnormal conditions (such as a short circuit) within a specified time. The working principle and structure of the isolating switch itself are relatively simple, but due to its large usage and high requirements for working reliability, it has a significant impact on the design, construction, and safe operation of substations and power plants. The main feature of the isolating switch is that it has no arc extinguishing ability and can only open and close circuits when there is no load current.

[0003] Disconnectors are generally used as high-voltage disconnectors, i.e., disconnectors with a rated voltage of 1kV or more. Commonly used disconnectors can be divided into single-column disconnectors, double-column disconnectors, and three-column disconnectors. During the production and assembly process of disconnectors, disconnectors are usually composed of mounting bases, insulators, and accessories for conductive parts. Due to the structural requirements of actual use, disconnectors commonly used for high voltage are usually large in size, and their mounting bases, insulators, and other structural parts are heavy. Existing disconnectors are usually assembled manually during the production and assembly process, and the assembly process is relatively complicated. In addition, due to the size and weight of some structures, manual assembly is time-consuming and labor-intensive, and the installation and production efficiency is relatively low. In view of this, we propose a production process for disconnectors to improve the efficiency of manual assembly during the production process of disconnectors.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0005] In order to solve the problems raised in the above-mentioned background technology, the technical solution of the present invention proposes a production process for disconnectors. On the one hand, the accessory slots of several groups of first accessory slots and second accessory slots are independently designed to complete the distribution of accessories required for the production and assembly of each group of disconnectors, and are placed in the interior of the accessory slots in sequence, so as to reduce the time consumption of searching for accessories during the manual assembly process. On the other hand, the present invention utilizes the insulator conveying structure of the first insulator conveyor belt and the second insulator conveyor belt to clamp the insulators required in the production and assembly process of the disconnectors in advance according to the direction of assembly and installation, thereby reducing the inconvenience of the high-weight insulator structure on the subsequent assembly process and improving the efficiency of assembly production.

[0006] The present invention provides a production process for an isolating switch, which specifically includes the following steps:

[0007] 1. Assembly preparation stage:

[0008] S1. Accessory feeding: Accessories required for the production of disconnectors are fed in through several groups of accessory conveying structures. The accessories required for the production of disconnectors are conveyed through several groups of accessory conveyor belts and transported to the inside of several groups of first accessory slots, so as to complete the distribution of accessories required for the production and assembly of each group of disconnectors and place them in the inside of the first accessory slots in sequence, so as to reduce the time consumption of searching for accessories during manual assembly. At the same time, since the accessories in each group of first accessory slots are all used for the production and assembly of the same group of disconnectors, the number of installed and uninstalled accessories can be clearly understood during the manual assembly process, which to a certain extent avoids the occurrence of phenomena such as missing or over-installed accessories.

[0009] S2. Insulator installation: The insulators required for the production of the disconnector are transported and fed through the insulator conveying structure. The insulators required for the production of the disconnector are transported separately through the first insulator conveyor belt and clamped and fixed in advance according to the installation direction of the insulators by several groups of clamping heads on the second insulator conveyor belt. Since the insulators are usually heavy and inconvenient to operate during the assembly process, the technical solution of the present invention utilizes the second insulator conveyor belt to clamp the insulators required for the production and assembly process of the disconnector in advance according to the installation direction, reducing the inconvenience caused by the high-weight insulator structure on the subsequent assembly process, facilitating the installation of the insulators during the subsequent assembly, and improving the efficiency of the overall assembly production.

[0010] S3. Bottom plate feeding: The bottom plates required for the production of the disconnector are fed through the bottom plate conveying structure. The bottom plates required for the production of the disconnector are respectively conveyed through the first bottom plate conveyor belt and then conveyed to the second bottom plate conveyor belt.

[0011] 2. Assembly stage:

[0012] S4. Assembly:

[0013] First, the motor assembly drives the assembly conveyor belt to the side where the assembly station is located. Several groups of first accessory slots and the accessories inside them on the assembly conveyor belt are moved to the side where the assembly station is located. The second insulator conveyor belt moves to the side where the assembly station is located. The insulators clamped and fixed on the second insulator conveyor belt move to the side where the assembly station is located. Simultaneously, the second bottom plate conveyor belt also moves the bottom plate above it to the side where the assembly station is located.

[0014] During assembly production, pull the handle of the first accessory slot to drive the first accessory slot to slide outward, so that the accessories inside the first accessory slot fall into the second accessory slot, so as to transfer the production accessories inside the first accessory slot on the assembly conveyor belt to the second accessory slot, so that the assembly conveyor belt can continue to operate without being affected by the assembly time process, and complete the assembly and installation of the insulator, base plate and other structures of the disconnector through the accessories. The assembled disconnector is transported to the subsequent process part through the discharge conveying structure.

[0015] In the technical solution of the present invention, a frame is further provided on the outside of the motor assembly, several groups of the accessory conveying structures and the insulator conveying structures are located on one side of the frame, the first bottom plate conveyor belt, the second bottom plate conveyor belt and several groups of the second accessory slots are respectively located on the other side of the frame, several groups of the first accessory slots, the second insulator conveyor belts and the assembly conveyor belts are respectively located above the frame, and the second insulator conveyor belts and the assembly conveyor belts are respectively controlled and driven by the motor assembly.

[0016] Furthermore, several groups of the accessory conveying structures also include a resistance shaft, which is located at one end of the accessory conveyor belt. The outside of the resistance shaft is covered with a resistance sponge to slow down the speed at which the accessories fall into the first accessory slot through the accessory conveyor belt.

[0017] Furthermore, an insulator installation station is provided on one side of the insulator conveying structure, which is used to set up a station to clamp and install insulators at several groups of the clamping heads on the second insulator conveying belt.

[0018] Furthermore, several groups of the first accessory slots are slidably installed above the assembly conveyor belt, several groups of the assembly stations are located on one side of the second accessory slot, and the discharge conveying structure also includes a discharge conveyor belt.

[0019] Effective Gain: In summary, the present invention proposes a production process for disconnectors. In the technical solution of the present invention, on the one hand, the accessory slots of several groups of first accessory slots and second accessory slots are independently designed to complete the distribution of accessories required for the production and assembly of each group of disconnectors and place them in sequence inside the accessory slots, thereby reducing the time consumed in searching for accessories during the manual assembly process. At the same time, because the accessories inside each group of accessory slots are all required for the production and assembly of the same disconnector, the number of installed and uninstalled accessories can be clearly understood during the manual assembly process, thereby avoiding the occurrence of missing or over-installed accessories to a certain extent.

[0020] On the one hand, the present invention utilizes the insulator conveying structure of the first insulator conveyor belt and the second insulator conveyor belt to clamp the insulators required in the production and assembly process of the disconnector in advance according to their installation direction, so as to reduce the inconvenience caused by the high-weight insulator structure to the subsequent assembly process and improve the efficiency of assembly production.
