、８ｃが布設され、ケーブル室。The circuit breaker 2 is housed in the circuit breaker chamber 1a, and the circuit breaker 2 is arranged so that it can be moved from the operating position shown in the figure to the test position shown by the chain line.
e, closes when circuit breaker 2 is in the operating position,
A disconnecting contact 3 is provided that opens while maintaining a predetermined insulation distance L1 when in the open position. The disconnecting contact 3 is supported by a power supply side contact 4a connected to the circuit breaker 2, a load side contact 4b, and a partition wall 1e, and is connected to the bus chamber 1.
It is composed of a panel-side contactor 5a on the power supply side introduced into the cable chamber 1c, and a panel-side contactor 5b on the load side led out to the cable room 1c. Both of the panel-side contacts 5a and 5b are similarly supported on the axis of a bottomed cylindrical insulating tube 6, and are connected to the partition wall 1.
Although not shown, the insulating cylinder 6 is screwed to the metal part 6 through a metal part 6a on its outer periphery. And board 1l
An insulating cylinder 6 is installed on the front side of the insulating cylinder 6 that covers the II & - contactors 5a and 5b when the circuit breaker 2 is moved between the operating position and the test position.
A shutter device having a shutter plate 7 that automatically opens and closes the opening of the shutter is provided. On the other hand, in the bus room 1b, three-phase busbars 8a and 8b orthogonal to the plane of the paper are connected to each of the panel side contacts 5a on the power supply side introduced from the above-mentioned cutoff chamber 1a.
, 8c was installed and a cable room.
ＩＣには負荷側の盤側接触子５ｂのそれぞれが接続され

っていた。In this configuration, when the circuit breaker 2 is in the test position, that is, when the front sides of the panel side contacts 5a and 5b are closed with the shutter plate 7, the panel side contacts 5a and 5b become high voltage charging parts.
, 5b and the shirt shirt plate 7 must have a specified withstand voltage value. However, in this case, since the tips of the panel-side contacts 5a and 5b are pointed, electric field concentration occurs, which causes the dimension L1 of the circuit breaker 2 in the pull-out direction to be small, and the depth dimension of the closed switchboard 1 to be There is a drawback that it requires a large amount of power, especially this
This was noticeable in the case of V-class ratings, and was an obstacle to downsizing closed switchboards.

図るものである。The gist of this invention is to achieve the above-mentioned object by providing a jack-shaped device-side contact installed behind a drawer-type electrical device housed in a switchboard, and a jack-shaped device-side contact that faces the device-side contact so as to be removable. A drawer type, comprising a plug-shaped panel-side contact supported on a partition wall in the distribution board via an insulating cylinder, and having a shutter device for opening and closing the front side of the panel-side contact as the electrical equipment moves. In a disconnecting contact for electrical equipment, the withstand voltage dimension is reduced by providing a cylindrical metal electric field relaxation member that covers the tip of the board-side contact and is located within the insulating cylinder.

殺する。Figures 1 and 2 are views showing essential parts of an embodiment of a drawer-type disconnecting contact for electrical equipment according to the present invention, with Figure 1 being a longitudinal sectional view when closed, and Figure 2 being viewed when opened. FIG. In the figure, parts that are the same as those in the conventional device shown in FIG. By covering the panel-side contacts 5a and 5b with a cylindrical electric field relaxation member 9, the drawer dimension is reduced to L3, and the dimension up to the shirt flap plate 7 is reduced to L4, and the depth dimension of the closed switchboard to be housed is reduced. Out. The electric field relaxation member is made of metal and has the above-mentioned cylindrical shape, and has a rounded front end that curves inward to cover the pointed tips of the board side contacts 5a and 5b. As a result, as mentioned above, the dimension L4 between the panel side contacts 5a, 5b and the shirt flap plate 7 can withstand the specified voltage value, and the insulating tube 8 is the same as the insulating tube of the conventional device shown in FIG. d, and the dimensions of the conductive parts of the device side contacts 4a and 4b are also shortened. Therefore, from these reasons, the depth dimension of the closed switchboard can be made shorter than the drawer dimension L3 of the circuit breaker, although it is not shown. In addition, the size is reduced by the reduction in the dimension L4 between the panel side contacts 5a, 5b and the shirt flap plate 7, which sufficiently offsets the cost increase due to the increase in the number of parts.
