Problems solved by technology

[0005] Therefore, how to provide a spring operating mechanism for a high-voltage circuit breaker must not only satisfy the performance, but also facilitate the installation, debugging, and maintenance of the motor, electromagnet, and buffer after being installed on the three-phase circuit breaker. Avoiding the risk of buffer oil leakage when the spring operating mechanism is switched between vertical and horizontal positions has become a technical problem that needs to be solved urgently in this field

Embodiment 1

[0033] see figure 1 , figure 2 , image 3 Shown is a spring operating mechanism and buffer module solution for a high-voltage circuit breaker.

[0034] see figure 1 , assuming that the spring operating mechanism of the high-voltage circuit breaker is used to connect with the circuit breaker, the outward direction is the X direction, and the direction perpendicular to the X direction is the Y direction, and the XOY plane is located in the plane where the large gear 11 of the energy storage module is located .

[0035] The solution includes a base module, an opening and closing spring module, an energy storage module, an energy storage shaft module, an output shaft module, a buffer module, a closing and tripping module, and an opening and tripping module during specific implementation. see Figure 4 , After the three phases of the spring operating mechanism of the high voltage circuit breaker are arranged side by side, the right side is the observation, operation and maint...

Embodiment 2

[0052] see Figure 4 , a three-phase high-voltage circuit breaker, A, B, C three-phase circuit breaker bodies are arranged side by side in parallel, and the spring operating mechanism in the first embodiment of the three is respectively fixed on the A, B, C three-phase circuit breaker ends and are parallel to each other. Electromagnets, motors, buffers, etc. are located on the outside where it is easy to adjust, which is convenient for installation, maintenance and debugging; at this time, the buffer modules are all tilted upward to the left, which effectively reduces the risk of oil leakage from the buffer modules; When the three phases of high-voltage circuit breakers are arranged side by side and the space is limited, it is convenient for the installation, commissioning and maintenance of the spring operating mechanism.

Embodiment 3

[0054] A single-phase high-voltage circuit breaker, which adopts the above-mentioned spring operating mechanism, and is fixed below the body of the single-phase high-voltage circuit breaker. At this time, the electromagnet, motor, buffer, etc. are all located at the lower side for easy adjustment, which is convenient for installation, Maintenance and debugging; at this time, the buffer modules are tilted upward to the upper right, effectively reducing the risk of oil leakage from the buffer modules.

Abstract

A spring operation mechanism for use with high-voltage circuit breakers: a closing and opening spring of an opening / closing spring module is arranged in a Y direction and is located at a left side of a large gear (11) in an X direction; a motor of an energy storage module is located at a bottom right side of the large gear in the X direction; a buffer module assumes a straight rod shape, and a direction from an oil cylinder (28.6) part at a tail portion thereof to a clamping fork (28.1) part, a head portion of which is used for connecting an output shaft module, forms an angle of 135° or close to 135° with the X direction; a hinge joint of the oil cylinder part at the tail portion of the buffer module and a base module is located at a right side of the large gear in the X direction; an electromagnet (16) of an opening and closing trip module is arranged at a top right side of the large gear in the X direction. The spring operation mechanism may be applied to a plurality of scenarios, such as vertical and horizontal operations and the like. Particularly in the case wherein a high-voltage breaker is three-phased and arranged in columns while space is limited, installation, debugging, and maintenance of the spring operation mechanism is convenient.

Description

technical field [0001] The invention relates to a spring operating mechanism of a high-voltage circuit breaker, belonging to the technical field of high-voltage power transmission and transformation circuit breakers. Background technique [0002] The operating mechanism is an important equipment in the field of high-voltage power transmission and transformation, and is an important part of the high-voltage circuit breaker. The opening and closing operations of the high-voltage circuit breaker are realized through the operating mechanism. [0003] When the spring operating mechanism of the existing high-voltage circuit breaker is installed on the circuit breaker in three-phase parallel arrangement, due to the limited space, it is inconvenient to install, debug and maintain the motor, electromagnet and buffer. The spring operating mechanism needs to be disassembled from the three-phase circuit breaker, which brings inconvenience to the debugging and maintenance work; at the sa...
