Abstract

The invention relates to a floor type intelligent control system measurement integrated device and a control protection method thereof. The present grid power supply system has no processing system for processing the inter-phase short circuit fault and the single-phase grounding fault. The fault of the power electronic equipment in the user community causes tripping of outgoing switches of substations and equipment damage and affects the normal power supply of users. The device comprises a box (1). A high voltage switch base (7) and a support (14) are installed at the bottom of the box. Threehigh voltage switches (9) are installed on the high voltage switch base. The top of the high voltage switches is provided with outgoing cables (8). The right side of the high voltage switch base is connected with a protective current transformer (11) and a zero sequence current transformer (10) through two connecting pipes. The protective current transformer is connected with one end of a high voltage meter (12) through the cable. The zero sequence current transformer is connected with the high voltage switches through the connecting pipe. The invention is used for the floor type intelligent control system measurement integrated device.

Description

Technical field: [0001] The invention relates to a power grid protection and control system, in particular to a floor-standing intelligent control system measurement integration device and a control and protection method.
