Drawer switch cabinet operation method and handle symbol principle

Operation method of drawer type switch cabinet

The propulsion interlocking mechanism of this equipment consists of three parts, which are composed of propulsion, interlocking and operation units. Then the push part of the drawer type switch cabinet is equipped with a push roller, and at the same time, there is a spiral groove on the push roller that can engage with the positioning piece on the bottom of the equipment drawer, and a front edge part of it. Lock the groove. When operating the drawer type switchgear, the front and back of the advancing rollers are fixed by the front fixed plate and the rear fixed plate.

The propulsion rollers of the switch cabinet protrude out of the front fixed plate. The hexagonal bushing limit wheels and positioning wheels generally have propulsion shafts with hexagonal holes. At the same time, screws are used to fix the propulsion shaft and propulsion wheels together. There is also a limit block on the limit wheel of the drawer switch, the front fixed plate is equipped with a stop, and there are three arc-shaped grooves on the circumference of the positioning wheel, which play the role of connection, test and separation. Finally, The front fixing plate of the drawer type switch cabinet is provided with a positioning elastic clip which can contact with the positioning wheel.

The interlocking part of the switchgear is composed of a bolt, a bracket, a spring, a fork lever, a bolt, a connecting rod, and a cross bar. It can not only solve the hidden dangers of the operation of the drawer switchgear, but also harmonize with the current situation. Compared with technology, it has the characteristics of small size. Usually this type of equipment rarely has a closing button, and generally uses an opening and closing handle, and any type of molded case circuit breaker can be installed in the drawer.

Drawer type switch cabinet operation steps

1. Install the rear sealing plate first, and then close the front door;

2. Operate the main shaft of the earthing switch and adjust it to the opening position;

3. Secondly, use the transfer truck (that is, the platform truck) to push the handle truck (when in the open state) into the cabinet (test position);

4. Then insert the secondary plug into the static socket (this time the drawer type switch cabinet test position indicator will light up), and then close the front middle door;

5. Finally, use the handle to push the cart from the test position (in the open state) to the working position (the corresponding indicator will also light up, and the test position indicator light will go out);

6. Close the circuit breaker trolley to complete the operation.

Handle symbol principle of drawer type switch cabinet

1. The principle of primary, secondary and electrical symbols;

2.The operation of the disk surface usually has a handle and a rotating shaft, and the meaning of the O symbol means that it is composed of an eccentric wheel fixed on the bottom of the cabinet, a rotating handle and a fixed block on the back of the drawer bottom, so it becomes a The mechanism that allows the drawer to move in and out, there are other mechanisms that can close and open the drawer door, and the mechanism that allows the drawer to be taken out of the cabinet. The handle of the drawer type switch cabinet can make the drawer have three positions: inserted operation, drawn out, and without load. The specific principle and symbols are shown in the following figure.

The above is the operation method of the drawer type switch cabinet and the principle of the handle symbol, I hope it can help everyone.
