Abstract
The utility model relates to power supply and distribution equipment applied in an electric power system and especially relates to a box-type ring network switch device. An inlet wire chamber is located on an upper portion of a cabinet body. A low pressure chamber is located on one side of the inlet wire chamber. A handcart chamber is located on a lower portion of the low pressure chamber. An outlet cable chamber is located on the lower portion of the inlet wire chamber and is isolated by an isolation plate. The inlet wire chamber is provided with a static contact. The handcart chamber is provided with a guide rail. A circuit breaker is installed on the guide rail. An arc extinguishing gas storage chamber is placed on the lower portion of the handcart chamber and is provided with an arc-extinguishing-gas temporary storage device. The outlet cable chamber is provided with an isolation switch and an outlet cable. The static contact passes through the circuit breaker, and then traverses an insulation sleeving arranged on the isolation plate and is connected to the isolation switch. The outlet cable is connected to an outlet terminal of the isolation switch. A layout of the device of the utility model is reasonable. The structure is compact and an operation is flexible. Overhauling is convenient. The isolation plate is additionally arranged so that safety of operation and maintenance personnel is guaranteed and generation of an accident is effectively avoided. Through designing the arc-extinguishing-gas temporary storage device, an electrical apparatus element in the switch equipment is effectively protected.
