Description

Parallel electrical box door control device

The creation is a parallel electric box door control device, in particular to open and close the power box door to control an angle of rotation of a connecting rod, thereby controlling whether the box door connected in parallel with the power box can be opened, When the power box door is turned off and the power is turned off, the door of the box door can be opened to avoid the safety maintenance of electric shock, and the connecting rod is controlled by the rotation angle to control whether the box door can be opened or not. Controlled by lateral shifting, it has the advantage of high control accuracy.

According to the electrical box, in parallel, as shown in Figs. The power box 1 is the main source of power supply for the parallel electrical box. The power source is redistributed to the box 2 application, and the power source is high voltage. During maintenance, if the power is not turned off, the box 2 is opened. If the operation is careless, it is easy to generate electric shock. Therefore, in order to prevent the above-mentioned lack, the manufacturer designs that when the power box 1 door 10 is opened, the box door 10 of the power box 1 simultaneously uncovers the power main switch in the power box 1 to make the power supply. Box 1 is powered off. In design, the box door 10 of the power box 1 is required to be opened first, and the box door 20 of the box 2 can be opened to prevent the box door of the box 2 from being opened at any time without the main power switch being turned off, and an electric shock problem occurs.

The above-mentioned conventional door door control method (such as the German Rittal manufacturer), as shown in FIG. 1 , is provided with a connecting rod 3 in the box of the electric box, and the connecting rod 3 can be closed when the box door 10 of the power box 1 is closed. When the door 10 is pushed up and laterally displaced by a predetermined distance, the catching member 31 positioned on the link 3 and laterally displaced synchronously with the link 3 and the card member 32 positioned on the box door 20 of the box 2 are stuck. Stay fixed, can not be arbitrarily opened (Figure 2). When the door 10 of the power box 1 is opened, the connecting rod 3 is laterally returned to the original position by the spring, and the position of the engaging member 31 and the member to be chucked 32 is shifted to the left and right (as shown in FIG. 1), and the box door 20 of the box 2 begins. It can be opened, so that the box door 10 of the power box 1 is opened, and the box door 20 of the box 2 can be opened.

The conventional control of the box door 20 of the box 2 is stuck in the following manner, and the following defects exist in the application:

1. The connecting rod 3 controls the jamming of the box door 20 of the box 2 in the lateral displacement mode, wherein the alignment accuracy between the latching member 31 and the card member 32 is very high, otherwise it is easy to be caused by the connecting rod 3 The displacement stroke error causes the above-mentioned interlocking door condition to be impossible.

2. When the box door 10 of the power box 1 is closed, the connecting rod 3 is driven by the box door 10 of the power box 1 to laterally compress the spring displacement; when the box door 10 of the power box 1 is opened, the connecting rod 3 is again replied by the spring. The force is returned to the original position. However, after using the operation for a period of time, the spring is prone to elastic fatigue, causing the lateral displacement point of the connecting rod 3 to slip to a preset position, resulting in control misalignment.
