Next, the operation will be explained. Conventionally, in this type of pull-out type switchboard, when pulling out the inner trolley device to the disconnection position or test position, the main circuit! Turn off the magnetic contactor (to)
After F operation, confirm that the main circuit is open and hold the opening of the face plate 1511 on the front of the stage car frame (from the handle of the inner dolly frame OP) to horizontally pull out the inner dolly frame. Contact α◆ on the power supply side and load side of the circuit,
The main circuit was disconnected at (e) and the temperature was reduced to °C. Note that the insertion operation, that is, the connection operation of the main circuit, was performed in a completely opposite manner to the above-mentioned operation method.

The trolley pull-out device of the conventional double trolley pull-out type switchboard is configured as shown below, so it was necessary to operate the handle on the inner trolley frame from the face plate opening on the front of the stage car. Because the opening is narrow, the weight of the inner trolley, and the contact pressure of the main circuit contactor are large, disconnecting and inserting the inner trolley requires more operating force and careful checking before and after operation.

In addition, although the trolley body is grounded, the handle of the inner trolley body carrying the main circuit charging components must be manually operated.
Furthermore, there is a sense of anxiety about incorrect operation, and the opening cannot have a sufficient structure to prevent dust, protect the panel from foreign specifications, and protect against blasts caused by accidents inside the switchboard frame. There were drawbacks such as.

This invention has been made in order to eliminate the above-mentioned drawbacks of the conventional stage car.The opening for operating the inner bogie provided in the face plate on the front of the conventional stage car has been replaced with an operating mechanism that engages with the inner bogie. An operation box with a built-in operation mechanism is provided, and the operation lever directly connected to the operation mechanism can be rotated from the outside of the outer trolley face plate to easily and reliably insert and disconnect the inner trolley.Furthermore, the main circuit The double trolley drawer eliminates the operator's anxiety because the charging equipment loading trolley frame is not directly touched, and since there are no openings, it is fully dustproof, has a protective structure, and provides blast protection against internal accidents. Providing panel operation pull-out devices for type switchboards,
It is intended to.

An embodiment of the present invention will be described below with reference to the drawings.

Note that rnJ (2) is an intermediate bearing of the rotating shaft 4, and (2) is an end bearing.

Figure 9 shows the state in which the inner truck is disconnected and the inclined truck is carried out from the switchboard main body, and Figure 10 shows the switchboard main body after the cart has been removed, and Figure 11 shows the inclined cart frame after the inner cart has been removed. Figure 12 shows the inner truck frame body carried out from the tilting truck, and the constituent parts are the same as those described above.

Next, an explanation will be given of the operation of the panel operation pull-out device for the double-carriage pull-out type switchboard configured as described above. This type of drawer-type switchboard consists of a slanted bogie frame that engages with the switchboard frame body 11) and an inner bogie frame 09 that moves horizontally within the thickness of the slanted platform and houses the main circuit equipment. The conventional opening for operating the inner trolley has been eliminated from between the face plates on the front of the frame ring, and there are four operating levers and 811 inner levers for operating the panel! Consisting of operating mechanism members 1a to 1a for horizontally moving the inner truck by engaging the guide seat on the front side of the L frame,
It consists of four operation boxes that house this operation mechanism. The relationship between the main body of the switchboard frame, the inclined truck, and the inner truck is the same as in the past.

Figures 4 and 6 show the state in which the inner bogie 0υ is inserted into the main circuit.
The operating lever... is inserted through the four grooves of the operating box.
It is directly connected to a circular lever shaft, and this circular lever is fixed to the operating mechanism rotating shaft 4.

In other words, the insertion of the operation lever and the operation of the disconnection 7 are transmitted as the rotational operating force of the rotating shaft, and the rotating arm member provided at one end of this rotating shaft is guided by the guide provided on this rotating arm member. and a guide S on the front of the inner truck that engages the rotational movement of the guide roller with the guide roller.
By converting the motion into horizontal motion at the St+ section, horizontal operations for inserting and disconnecting the inner truck are made possible. Note that FIGS. 7 and 8 show the inner bogie disconnected state.

Although this example describes the case of a combination type main circuit component, the part corresponding to the inner trolley may be a circuit breaker, other opening/closing equipment, or other drawer equipment. ＜The diagram shows a single stack configuration °C
However, it is also possible to have a multi-stage stacked structure, and the same effects as in the embodiment described above can be obtained.

As described above, according to the present invention, in a double bogie device consisting of an inner bogie frame containing the main circuit forming members and equipment and a diagonal bogie housing the inner bogie frame, the operation provided on the front surface of the C diagonal bogie, that is, the front surface of the switchboard. By rotating the lever, the inner bogie body is moved horizontally and the circuit can be connected or disconnected, so the circuit can be charged just like a conventional device that operates the inner bogie directly from the opening of the diagonal bogie face plate. I was relieved of my anxiety about parts and incorrect operation, and the serious condition of the inner truck was resolved.
Since the large operating force generated from the contact pressure of the main circuit contactor can be easily and reliably operated with a single operating lever, there is little need for caution when operating the inner trolley and confirmation checks before and after operation. By eliminating the droop part of the plate, it is possible to create a structure that is waterproof, drip-proof, protects against foreign specifications, etc., and is fully capable of dealing with fanning in the event of an internal accident, resulting in higher precision than before. This has the effect of providing a panel operation pull-out device for a 2N truck that allows light and reliable operation.
