There are several optional High Voltage Switchgear concern: 1 whole group Priorities cabinet cabinet arrangement and operation of surface position is considering making factory inside the separator, terminal guards, bus segment support issues such as proper application basis Jieshou center cabinet, floor plans and site to be consistent with the actual position of the inlet and outlet, especially to the right side shows the direction of the cabinet operations, in order to make high-voltage cabinet arrived at the scene after the successful installation. Often at first to downplay the device arrived at the scene found that the site does not meet the requirements, leading to rework. 2. Inlet and outlet switchgear conventional inlet and outlet There are basically two kinds of connections: (1) Cable Cable chamber is connected into the outlet, (2) into the outlet from the top of the cupboard wall bushing lead, and with the bus bridge is connected to the bridge and then by bus Wall bushing connected to overhead lines. A small number of users, introduced by cable cable rack Roof, cabinet connection Roof connection, a separate security grid. Users provided when ordering a system diagram and the standard program, but into the round can not fully express very clearly, the user should the actual site installation requirements technical agreement was duly explained, difficulties to the site installation. The circuit breaker breaking capacity on a system diagram the right choice, the choice of circuit breaker, breaker models show, rated voltage, rated current things, circuit breaker capacity must be selected. User drawings, circuit breaker capacity is not selected, so the manufacturer for difficult engineering design, breaking capacity selection should be based on the system short-circuit parameters to select, if manufacturers do not understand the system it is very difficult to make the right short-circuit parameters Choose. Some users also drawings, the system does not consider the case of short-circuit parameters, blindly choose high breaking parameters, resulting in unnecessary waste of money. Correct choice of breaking capacity counters in the home is very important, it is necessary to ensure safe operation, but also taking into account the lower cost of the product is divided into semi-enclosed high voltage switchgear and high voltage switchgear metal enclosed high voltage switchgear two categories. So what is a semi-enclosed high voltage switchgear? Semi-enclosed high voltage switchgear in the various components of the ground from high voltage switchgear 2. 5m or less installed in a grounded metal housing, 2. 5m and above capacitor contactors busbar disconnectors or no metal shell closed. Its metal shell, the outer conductor ground.interphase distance should comply with the relevant specifications. High Voltage Switchgear structure type is fixed (indoor type), models GBC, GG-IA. Breaker installation location and the surplus into floor-type. The basic features are simple structure, easy manufacture, inexpensive Mingguang counters in the home, and can clearly see the switching state introduce line isolation switch; however Ningguo center cabinet, 2.5m high to allow the live components exposed outside the cabinet, and no compartment, security is poor. It has been used less. Bozhou in home cabinets | counters in the home | Anhui Yu-liang Electric offers by the Anhui Electric Co., Ltd. Yu Liang. Yu Liang Anhui Electric Co., Ltd.
