摘要： PROBLEM TO BE SOLVED: To provide a metal closed type switchgear compatible with an internal arc accident without changing the contour dimension of the metal closed type switchgear and its installation area. SOLUTION: The switchgear includes: a first metal closed type switchgear 100 having a loaded blocker chamber 101, a bus-bar chamber 103 arranged at the back of the blocker chamber, and a cable-current transformer chamber 102 arranged at the back of the bus-bar chamber 103; a second metal closed type switchgear 200 having a blocker chamber 201 which is arranged at the side of the blocker chamber 101 at the lower side of the first metal closed type switchgear 100, and includes a partitioning plate 241 located below the partitioning plate 141 of the blocker chamber 101, a bus-bar chamber 203 arranged at the back of the blocker chamber 201, and a cable-current transformer chamber 202 arranged at the back of the bus-bar chamber 203; and common pressure-discharging chambers 205, 206 which are arranged above the blocker chamber 201 of the second metal closed type switchgear 200, and above the cable-current transformer chamber 202.

摘要： PURPOSE:To make a low switch-board by moving a backward shutter, which covers the front of upper and lower disconnection parts when the main circuit of an enclosed switch-board is disconnected by movement of a breaker by rotation by about 90 deg. in connection. CONSTITUTION:In disconnection, the breaker 5 of an enclosed switch-board 30 is drawn out forward and upper and lower contact movers 6a and 6b are separated from the upper and lower disconnection parts 2 and 3 of a switch- board fixation part 1. When the slider 8 of the breaker 5 is separated from the roller 11 of an operation lever 9, a vertical lever 13 slides along a rod 16 and upper and lower shutters 18 and 21 cover the upper and lower disconnection parts 2 and 3. When the breaker 5 is switched on, the slider 8 pushes down the roller 11 of the lever 9 and the lever 13 rotates by approximately 90 deg. and moves backward the upper and lower shutters 18 and 21. Thereby a low switch- board is made and a charge part is isolated in disconnection, with improved safety.
