Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 The shown assembly drawing of the inflatable cabinet of the present invention includes a cabinet body, a cabinet door, a front cabinet assembly 3, an inflatable unit 2 and a liquid crystal controller 1 arranged on the cabinet door. The liquid crystal controller 1 can realize functions such as program editing, parameter setting, and fault detection. At the same time, a circuit breaker, a three-position switch opening and closing button, and a remote control switch are configured to realize the circuit breaker and the three-position switch close control operation. Inflatable unit 2 is used for circuit breaker and three-position switch assembly. Front cabinet assembly 3 is used for the assembly of secondary terminal blocks, transformers, and energy storage capacitors.

Abstract

The invention relates to a medium-low voltage switch cabinet and a servomotor drive mechanism thereof. The medium-low voltage switch cabinet specifically comprises a circuit breaker servomotor, a three-position switch servomotor and a PWM driver, wherein each moving contact of a circuit breaker is connected with a main shaft of the circuit breaker servomotor through a circuit breaker drive mechanism; the moving contact of a three-position switch is connected with the main shaft of the three-position switch servomotor through a three-position switch drive mechanism; and the PWM driver is in control connection with the circuit breaker servomotor and the three-position switch servomotor. According to the medium-low voltage switch cabinet, a motor mechanism is applied to a C-GIS product to replace a spring mechanism of a traditional circuit breaker, so that mechanical movement faults, such as incomplete closing and excessive closing force of traditional equipment are avoided; the faults, such as switch burnout caused by heating of the contacts of a conductive system are avoided; and meanwhile, the time-consuming and labor-intensive debugging and testing processes of the traditional equipment are also saved.

Description

technical field [0001] The invention relates to a medium and low voltage switchgear and its servo motor drive mechanism, which belongs to the technical field of electric power system switchgear. Background technique [0002] Most of the C-GIS (40.5kv) inflatable cabinet products at home and abroad are composed of traditional mechanical motion operating mechanism and spring operating mechanism. Due to the large number of moving parts of the traditional mechanism and the existence of assembly errors, when the product design is completed, the circuit breaks The opening distance of the three-position switch is difficult to meet its technical requirements. There are mechanical movement faults such as insufficient closing force of traditional equipment and excessive closing force. In the design process, it is necessary to continuously debug various technical parameters of the entire product, which consumes a lot of manpower and material resources.
