Description
本发明属于高压开关技术领域,具体涉及一种三相断路器用机械联动传动***和三相断路器。The invention belongs to the technical field of high-voltage switches, and in particular relates to a mechanical linkage transmission system for a three-phase circuit breaker and a three-phase circuit breaker.
随着全球电力***的发展及对电力***运行可靠性要求日益提高,六氟化硫气体绝缘金属封闭开关设备(Gas Insulated metal-enclosed Switchgear,简称GIS)因其具有结构紧凑、可靠性高、抗震性能好,噪音低和维护工作量小以及不受外界环境条件影响等优点,在电力***中得到广泛应用。With the development of the global power system and the increasing requirements for the reliability of power system operation, the gas-insulated metal-enclosed switchgear (GIS) of sulfur hexafluoride is characterized by its compact structure, high reliability and earthquake resistance. It has the advantages of good performance, low noise and low maintenance workload, and is not affected by external environmental conditions, and is widely used in power systems.
目前的252kVGIS用断路器大多为分相设计,每相各配一台机构,一台三相断路器需要配置三台操作机构,生产成本较高。三相之间采用电气联动,由于电气联动受外界影响因素较多,容易出现非全相运行,影响供电***安全性,针对此问题,现有技术中也有采用三相机械联动的,三相机械联动是通过传动连杆等部件的机械连接,实现三相断路器的分合闸操作,提高三相同期可靠性,避免非全相运行,从根本上避免了三相电气联动的不可靠性,并且,使用一台操作机构控制断路器三相,降低了三相断路器的制造成本。实际上,现有的使用三相机械联动传动***中,操动机构和传动连杆等零部件分别独立地安装在三相断路器本体上,这使得断路器安装较为复杂,安装繁琐,不利于断路器的模块化生产。Most of the current circuit breakers for 252kV GIS are of phase-separated design, each phase is equipped with one mechanism, and one three-phase circuit breaker needs to be equipped with three operating mechanisms, and the production cost is high. Electrical linkage is used between the three phases. Since the electrical linkage is affected by many external factors, it is prone to non-full-phase operation, which affects the safety of the power supply system. In response to this problem, there are also three-phase mechanical linkages in the prior art. The linkage is to realize the opening and closing operation of the three-phase circuit breaker through the mechanical connection of the transmission link and other components, improve the reliability of the three-phase synchronization, avoid non-full-phase operation, and fundamentally avoid the unreliability of the three-phase electrical linkage. Moreover, using one operating mechanism to control the three-phase circuit breaker reduces the manufacturing cost of the three-phase circuit breaker. In fact, in the existing three-phase mechanical linkage transmission system, components such as the operating mechanism and the transmission link are independently installed on the three-phase circuit breaker body, which makes the installation of the circuit breaker complicated and cumbersome, which is not conducive to the Modular production of circuit breakers.
