Embodiment 1 FIG.
Embodiment 1 of the present invention will be described with reference to FIGS. 1 and 2 are a front view and a side sectional view of a switchgear according to the present invention. In the housing of the switchgear 1, a drawer-type circuit breaker 5 is disposed in a lower stage, and a drawer-type auxiliary device including an instrument transformer 30 is disposed in an upper stage corresponding to upper and lower sides of the drawer-type circuit breaker 5. In addition, the drawer-type auxiliary equipment including the instrument transformer 30 is arranged in the drawer-type circuit breaker 5 in an attached state. The draw-out type auxiliary equipment including the draw-out type circuit breaker 5 and the instrument transformer 30 are housed in cradles 40 and 60 having the same configuration.
A branch bus 3 branches off from a common bus 2 of the switch gear 1 and is connected to a conductor 4 for fitting with a terminal of a circuit breaker 5. The terminals of the circuit breaker 5 are fitted with the conductors 4 and 6 on the switchgear side in the operating position. A conductor 7 is attached to the conductor 6, and a high-voltage cable 8 is attached to the conductor 7.
The conductor 7 connected to the high-voltage cable 8 is branched from the conductor 9 for connecting to the instrument transformer 30 and is connected to the conductor 10 for fitting with the terminal of the drawer-type cart 11.
These conductor 4, conductor 6, conductor 7, conductor 9, and conductor 10 are configured as fixed-side conductive portions in the switchgear 1.

8 and 9 are a perspective view and a side sectional view showing the positional relationship between the circuit breaker 5 and the cradle 40 while the circuit breaker 5 is moving from the “disconnection position” to the “operation position”. In this state, the metal fitting 12 of the circuit breaker 5 has not fallen into the hole 15 or the hole 16 provided in the cradle metal fitting 14, so that the circuit breaker 5 cannot be set to the "closed" state.
FIGS. 10 and 11 are a perspective view and a side sectional view showing a positional relationship between the circuit breaker 5 and the cradle 40 when the circuit breaker 5 is in the “operating position”. In this state, the metal fitting 12 provided on the circuit breaker 5 has fallen into the hole 16 provided on the rear of the cradle metal fitting 14, and the "close" operation of the circuit breaker 5 is enabled.
Thus, the circuit breaker 5 can be set to the “closed” state only in the “operating position” and the “disconnection position”.

Embodiment 2 FIG.

The diameter of the wheel and the width of the wheel are the same as those of the circuit breaker 5. Therefore, rail components of the same cradle can be shared. Further, the same members can be commonly used for drawing out the draw-out type devices such as the circuit breaker 5 and the instrument transformer 30 out of the switchgear 1.
It is assumed that the width of the drawer type trolley 11 on which the instrument transformer 30 is mounted is different from the size of the circuit breaker 5. Here, the size of the lateral width is illustrated for convenience. The dimension from the floor of the drawer type trolley 11 on which the instrument transformer 30 is mounted to the floor of the cradle 50 mounted on the trolley is different from the dimension from the floor of the circuit breaker 5 to the floor of the cradle 40. Here, the size from the floor is shown larger for convenience. The dimensions of the terminals of the cart 11 are aligned with the terminals of the breaker 5 in the height and width directions.

The secondary side of the instrument transformer 30 is connected to the bogie 11 by providing a female-side insertion port 22 of a control connector, and fitting a male-side control connector (not shown) to this.
When a control connector is connected to the secondary side of the instrument transformer 30 and a control voltage is applied, a high voltage is induced on the primary side of the instrument transformer 30. At this time, if the primary side is touched, an electric shock is caused. Therefore, in the case of the dolly 11 of the drawer type instrument transformer 30 shown in FIG. 2, the control connector can be electrically and mechanically connected only when the dolly 11 is in the "operation position". It is required to do so.
This request is realized by the metal fitting 18 as a fixing member provided on the carriage 11 shown in FIGS. 14, 15 and 16, and the metal fitting 14a as a fixing tool of the cradle 50 shown in FIG. This structure will be described in detail below.
