Abstract
The utility model relates to the technical field of high-voltage combined electric appliances, and specially relates to a bilateral protection-bus-contact three-in-one semi-closed combined electric appliance. Bus protection intervals are disposed on two sides of a bus-tie cell. The bus-tie cell is disposed on a chassis. The bus protection interval comprises a left lead-out bushing and a right lead-out bushing. A right side of a three-link under the left lead-out bushing is connected with a breaker through an earthing switch, a disconnecting switch, and a current transformer. A left side of a three-link under the right lead-out bushing is connected with a breaker through an earthing switch and a disconnecting switch. A left side of the three-link under the left lead-out bushing is connected with the disconnecting switch, the earthing switch, a voltage transformer, and a lightning arrester. A right side of the three-link under the right lead-out bushing is connected with the disconnecting switch, the earthing switch, a voltage transformer, and a lightning arrester. The bus protection intervals disposed on two sides of the bus-tie cell are arranged symmetrically. Lower parts of the three-links are supported by height adjustable support rods. The combined electric appliance is characterized by compact structure, reasonable layout, small floor area, and low cost.
Description
Technical field
The utility model relates to a kind of high pressure combined electrical apparatus technical field, and specifically a kind of bilateral is protected the three-in-one semiclosed combined electrical apparatus of female connection.
Background technology
