Abstract

The invention discloses a combined type high-voltage composite apparatus and a unipolar structure of the combined type high-voltage composite apparatus. The unipolar structure comprises a breaker which moves along a leftward-rightward divide-shut brake, wherein two current transformers which are arranged at intervals in a left-right mode are vertically and fixedly arranged at the upper portion of the breaker, a straight line transmission type three-station isolated grounding switch which moves along the leftward-rightward divide-shut brake is fixedly arranged at the upper portion of the right side current transformer, a line incoming casing pipe unit which is inclined in the upper right direction is fixedly arranged at the right end of the three-station isolated grounding switch, and a line outgoing casing pipe unit which is inclined in the upper left direction is fixedly arranged at the upper portion of the left side current transformer. Space is fully utilized due to the arrangement, and the combined type high-voltage composite apparatus has the advantages of being simple in structure and reasonable in arrangement. More importantly, the vertical installation mode is adopted by all the monopoles, therefore, loads are evenly borne by interphase transmission connection parts, and the mechanical stability is good.

Description

technical field [0001] The invention relates to an SF6 gas-insulated fully-enclosed composite high-voltage combined electrical appliance and its single-pole structure. Background technique [0002] Combined electrical appliances are devices that combine two or more high-voltage electrical appliances into a whole according to the main wiring requirements of the power system, and each high-voltage electrical appliance still maintains the original specified performance. According to the insulation structure, it is divided into open type and fully enclosed type. Combined electrical appliances are generally arranged with multi-poles, and each single pole is an independent structure. Therefore, the selection and assembly combination of high-voltage electrical appliances in single-phase has a great impact on the overall performance of the entire combined electrical appliance (such as structure, size, phase-to-phase transmission synchronization, mechanical stability, etc.) Sex, etc....
