The utility model comprises cabinet, and cabinet inside is used by grounding plate and is separated into control room, breaker chamber, cable vault, main bus bar chamber and isolation ward; Control room, breaker chamber, cable vault, main bus bar chamber and isolation ward correspondence are provided with control room's cabinet door, breaker chamber cabinet door, cable vault's cabinet door, main bus bar chamber cabinet door and isolation ward cabinet door;
The control room is positioned at front side, cabinet top, and breaker chamber is positioned at front side, cabinet middle part, and the main bus bar chamber is positioned at cabinet top boss rectangular chamber, and the cable vault is positioned at the cabinet bottom, and isolation ward is between cable vault and main bus bar chamber; Interval between isolation ward and the breaker chamber arranges and forms an insulating space, and insulating space is connected with breaker chamber;
Be provided with lightning arrester, earthed switch in the cable vault.
Be provided with first isolating switch, second isolating switch, upper contact head box, following contact box and straight-through current transformer in the isolation ward; Upper contact head box and following contact box are arranged on the metallic plate of cutting apart breaker chamber and isolation ward; Straight-through current transformer is arranged on the metallic plate of cutting apart cable vault and isolation ward;
Main bus bar is indoor to be divided into first bus-bar room and second bus-bar room by dividing plate; Be connected with the first bus-bar room bus in first bus-bar room, be connected with the second bus-bar room bus in second bus-bar room.
The first bus-bar room bus and the second bus-bar room bus of first bus-bar room and the output of second bus-bar room, respectively with isolation ward in first isolating switch be connected with second isolating switch, first isolating switch is connected with the upper contact head box by the copper bar bus simultaneously with second isolating switch, is connected with lightning arrester, earthed switch after the copper bar bus of following contact box output passes straight-through current transformer.
The utility model beneficial effect is as follows:
The mid-cabinet of the utility model is domestic the first, adopt this mid-cabinet after because cabinet top is provided with the double-bus chamber, used the mode of two-way bus, the two-way bus adopts different electric power system power supplies, guaranteeing a power supply reliability and continuity, has very high practicality.
