Problems solved by technology

In order to express the composition and working principle of the electrical control system of production machinery, and at the same time facilitate the installation, commissioning and maintenance of equipment, the electrical components and connection relationships in the system are reflected in certain drawings, and are represented by prescribed graphic symbols on the drawings Each electrical component, and each electrical component is explained with text symbols. The electrical schematic diagram has a simple structure and clear layers. It is suitable for researching and analyzing the working principle of the circuit, and can provide help for finding faults. It is also the basis for compiling electrical installation wiring diagrams. Therefore, in The design department and production site are widely used, and the power distribution cabinet often becomes a very important carrier, which can meet the requirements of each electrical component in the circuit design and be reliably fixed in the determined position in the cabinet, which is convenient for the operator to operate and view. However, in the existing production, it is inevitable that there will be equipment failures or changes in production requirements. Sometimes it is necessary for the operator to perform maintenance operations when the power distribution equipment is in a live state. In this way, the personal safety of the operator is critical There is a considerable degree of danger

Embodiment 1

[0034] Such as Figures 1 to 3 As shown, the safety distribution cabinet of this embodiment includes a top board, a bottom board, and a rear side board.

[0035] 1. The open box body formed by the left side plate and the right side plate, the open box shape constitutes the space for the distribution cabinet to install each power distribution device, and the corresponding switches and circuits are correspondingly arranged in the space. In this embodiment, a front frame 23 is formed along the open box body, and the front frame 23 defines the positions for installing the front door 2 on the front of the power distribution cabinet, and the subsequent front doors are arranged at these positions. In this embodiment, the front door includes a left door 21 and a right door 22, and the power distribution cabinet is opened and closed through the doors on both sides. Any of these doors can be opened and closed individually. The power distribution cabinet is a complete set of equipment ...

Embodiment 2

[0049] On the basis of Embodiment 1, a grounding wire is added to the bottom of the box body, and the grounding wire is connected to the bottom of the rectangular box body of the distribution box to connect the distribution box The static electricity on the ground is timely introduced to the ground for release. Since there are many charged wires at the bottom of the distribution box, in order to overcome the current reverse transmission from the connected grounding wire to the rectangular box of the distribution box when some wires leak, which will cause electric shock danger, the present invention also adds an electric wire on the grounding line. A diode, the positive terminal of the diode is connected to the distribution box body, when there is electrostatic charge accumulated on the distribution box body, the diode conducts, and the electrostatic charge is conducted to the ground, reducing the harm of static electricity to the human body; at the same time Utilizing the one-...

Embodiment 3

[0051] The safe distribution cabinet of this embodiment, on the basis of Embodiment 1, the box is also equipped with:

[0052] A humidity sensor is arranged in the box to detect the real-time humidity inside the box;

[0053] a comparator, connected to the humidity sensor to compare the real-time humidity with a preset humidity;

[0054] A dehumidifier connected to the comparator to dehumidify when the real-time humidity is greater than the preset humidity.

[0055] The humidity sensor is arranged in the box body, and can detect the real-time humidity inside the box body. The comparator is connected with the humidity sensor, and the humidity sensor sends the detected real-time humidity signal in the cabinet to the comparator, and the real-time humidity in the cabinet detected by the humidity sensor is compared with the preset humidity in the comparator. When the real-time humidity is greater than the preset humidity, the comparator sends out a dehumidification signal. The d...
