Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of porcelain column circuit breakers, in particular to the field of porcelain column circuit breaker assembly, and specifically refers to a porcelain column circuit breaker opening and closing position debugging tool. Background Art
[0002] With the continuous development of domestic and foreign economies, the demand for electricity is also increasing. In areas where there are no geographical restrictions, porcelain column circuit breakers have been vigorously developed due to their price advantages. The more conventional structure of porcelain column circuit breakers is: arc extinguishing chamber and other high-voltage components are on the top, operating mechanism components are on the bottom, supported by pillar porcelain sleeves in the middle, and the arc extinguishing chamber transmission components are connected to the operating mechanism through pull rods inside. However, due to the limitation of processing level, the size of each component cannot meet the standard requirements, resulting in excessive cumulative errors, resulting in the arc extinguishing chamber opening and closing positions cannot be met. At this time, it is necessary to add a gasket between the pull rod and the operating mechanism to adjust the positioning so that the opening and closing positions are within a reasonable range.
[0003] The installation height of the porcelain column arc extinguishing chamber is relatively large. The height of the 550kV porcelain column arc extinguishing chamber reaches more than 7 meters. During the factory debugging process, it is necessary to measure the opening and closing dimensions at high altitude, which involves the risk of working at high altitude. When the measured dimensions are not met, the arc extinguishing chamber and the support must be disassembled as a whole. After lifting, the adjustment gasket must be installed between the pull rod and the output shaft of the operating mechanism. At this time, there is a risk of porcelain sleeve collision. To reinstall the connection, the opening and closing dimensions must be measured at high altitude again, which involves the risk of working at high altitude.
[0004] In order to solve the above problems, a special fixture for debugging the opening and closing positions of porcelain column circuit breakers is designed. During the installation and debugging process, the fixture cylinder and fixture connecting rod are used to replace the pillar porcelain sleeve and pull rod in normal products, which ensures the opening and closing position positioning, reduces the working height, reduces high-altitude operations, and improves the convenience and safety of installation. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a porcelain column circuit breaker opening and closing position debugging tool, which solves the problem of high-altitude operation while ensuring the opening and closing positions, and improves the convenience and safety of installation.
[0006] The utility model is realized through the following technical scheme, and provides a fixture for debugging the opening and closing positions of a porcelain column circuit breaker, comprising a fixture cylinder installed on an operating mechanism, the upper end of the fixture cylinder being connected to an arc extinguishing chamber, a fixture connecting rod being installed in the fixture cylinder, the fixture connecting rod extending in the up-down direction, the length of the fixture connecting rod being greater than the length of the fixture cylinder, the upper end of the fixture connecting rod being connected to a transmission component of the arc extinguishing chamber, a gasket being installed on an output shaft of the operating mechanism, the upper end surface of the gasket being connected to the fixture connecting rod, and the gasket being installed on the output shaft of the operating mechanism.
[0007] The utility model provides a tooling tube to replace the pillar in a normal product to play a supporting role. The height of the tooling tube is much lower than the height of the pillar, which is convenient for measuring the closing position. The tooling connecting rod is provided to replace the pull rod in a normal product. The closing position is judged according to the position of the tooling connecting rod, so as to select a suitable gasket, which can play a role in adjusting the gap. Through continuous debugging and selecting a suitable gasket, the assembly of the porcelain column circuit breaker can be completed.
[0008] As an optimization, the height difference between the tooling connecting rod and the tooling tube is equal to the height difference between the pillar and the pull rod. The setting of this optimization scheme can reduce the error and ensure that the selected gasket height can also be used when assembling a normal pull rod.
[0009] As an optimization, the upper and lower ends of the tooling tube are respectively installed with connecting flanges, the upper end of the tooling tube is connected to the arc extinguishing chamber through the connecting flange, and the lower end of the tooling tube is connected to the operating mechanism through the connecting flange. The setting of this optimization scheme facilitates the detachable connection between the upper end of the tooling tube and the arc extinguishing chamber, and facilitates the detachable connection between the lower end of the tooling tube and the operating mechanism.
[0010] As an optimization, a connection hole is provided on the tooling connecting rod, and the tooling connecting rod and the arc extinguishing chamber transmission component are detachably connected through a pin shaft passing through the connection hole. The setting of this optimization scheme facilitates the detachable connection between the upper end of the tooling connecting rod and the arc extinguishing chamber transmission component while ensuring normal transmission.
[0011] As an optimization, the lower end of the tooling connecting rod is provided with an axial hole, and the upper end of the output shaft is installed in the axial hole. The setting of this optimization scheme facilitates the connection between the tooling connecting rod and the output shaft, and at the same time facilitates the gasket to adjust the connection distance between the output shaft and the lower end of the tooling connecting rod.
[0012] The beneficial effects of the utility model are as follows: the utility model reduces the installation height of the porcelain column by designing the tooling tube and the tooling connecting rod, which facilitates the measurement of the opening and closing positions. The tooling ensures the positioning of the opening and closing positions, reduces the working height, reduces high-altitude operations, improves the convenience and safety of installation, has the characteristics of simple structure, easy manufacturing, safety and reliability, and has good practicality and promotion prospects.
