In order to improve the safety of the distribution network, the use of electric operating mechanism for ring closing and power exchange has gradually become a necessary function of the new intelligent distribution ring main unit. However, most of the traditional ring main unit has not been equipped with electric operating mechanism due to the difficulty of transformation, and many opening and closing actions still need to be manually operated by the staff, so the personal safety of the staff can not be guaranteed. The purpose of this paper is to develop a portable universal remote intelligent control device for ring main unit, which is used to replace manual operation to complete the switching operation, so as to reduce the possibility of safety accidents. The device adopts portable and modular design, so it is easy to install and disassemble. Modular adapter design can be applied to different specifications of ring main unit in power system to ensure the operation reliability of traditional ring main unit. When the technology is mature, the device can be widely used in various types of remote control electric opening and closing operation of old ring main unit. It can improve work efficiency, avoid personnel safety risk caused by manual operation in short distance on site, and can also be used as the emergency operation device of existing new intelligent distribution ring main unit, which has a wide application prospect. |
