Description

Technical Field

[0001] The utility model relates to the technical field of industrial automation, and particularly relates to a protection component for a control cabinet. Background Technique

[0002] With the continuous improvement of industrial automation, as the core component of an industrial automation system, the safety and stability of a control cabinet are particularly important. There are various protection components for control cabinets on the market currently. They usually have functions such as dust prevention, water prevention, and shock absorption, but they are insufficient in electromagnetic shielding. In an environment with severe electromagnetic interference, the electronic components inside the control cabinet are easily interfered by external electromagnetic waves, resulting in a decrease in control accuracy, equipment failure, or even system paralysis. Therefore, developing a protection component for a control cabinet with high-efficiency electromagnetic shielding function is of great significance for improving the anti-interference ability and overall performance of the control cabinet. Content of the Utility Model

[0003] The purpose of the utility model is to provide a protection component for a control cabinet to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A protection component for a control cabinet, including a chassis, a mounting rack, and a cabinet door. An elastic pad is installed at the bottom of the chassis, a bottom plate is installed at the bottom of the elastic pad, a metal EMI lining is arranged on one side of the chassis, and an insulating layer is arranged on one side of the metal EMI lining. Two groups of mounting racks are installed on both sides inside the chassis. A sensor assembly is installed inside the mounting rack through bolts. The sensor assembly includes an ammeter, a voltmeter, a wattmeter, and a temperature sensor. A main circuit breaker is installed above the inside of the mounting rack through bolts. The front of the chassis is hinged and installed with a cabinet door through a hinge.

[0005] When in use, place the chassis stably at the designated position. The bottom plate can protect the elastic pad. The bottom plate is in direct contact with the ground. The elastic pad has a certain elasticity and can play a shock-absorbing role during the operation of the device, reducing vibration and abnormal noise. The inside of the chassis can provide an installation position for electrical equipment. When the chassis is in use, the metal EMI lining inside can provide an attenuation of 60 dB - 100 dB in the range of 20 MHz - 1 GHz. By being fixed inside the chassis and in the slots, it can be used for EMI shielding, as well as waterproof, dustproof, and ventilation sealing. The insulating layer has good insulation performance and can prevent electromagnetic coupling between the metal EMI lining and the components inside the control cabinet. Through the combined use of the metal EMI lining and the insulating layer, it can effectively shield the interference of external electromagnetic waves on the components inside the chassis.

[0006] Preferably, a controller is installed on one side above the front of the cabinet door, and buttons are arranged on the front of the cabinet door. The controller adopts a PLC control system and is electrically connected to the electrical equipment inside the device. It is the core equipment in the control cabinet, responsible for executing predetermined logical operations and control tasks, and complex automatic control can be achieved through programming.

[0007] Preferably, a top cover is fixedly installed on the top of the chassis.

[0008] The chassis and the electrical equipment inside the chassis can be protected through the top cover.

[0009] Preferably, heat dissipation windows are provided inside the chassis.

However, after understanding the disclosure of the present application, various changes, modifications, and equivalents of the methods, apparatuses, and / or systems described herein will be apparent. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein, but rather, changes that will be apparent after understanding the disclosure of the present application may be made, except for operations that must occur in a specific order. In addition, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0020] The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, apparatuses, and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0021] Throughout the specification, when an element (such as, a layer, region, or substrate) is described as "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it may be directly "on", "connected to", "coupled to", "above", or "covering" the other element, or there may be one or more other elements intervening therebetween. In contrast, when an element is described as "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly above" another element, or "directly covering" another element, there may be no other elements intervening therebetween.

[0022] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0023] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or parts, these components, elements, regions, layers, or parts are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or part from another.

The bottom plate 103 can protect the elastic pad 102. The bottom plate 103 is in direct contact with the ground. The elastic pad 102 has a certain elasticity and can play a shock-absorbing role during the operation of the device, reducing vibration noise. The inside of the chassis 1 can provide an installation position for electrical equipment. When the chassis 1 is in use, the metal EMI lining 104 inside can provide an attenuation of 60 dB - 100 dB in the range of 20 MHz - 1 GHz.

The insulating layer 105 has good insulation performance to prevent electromagnetic coupling between the metal EMI lining 104 and the components inside the control cabinet. Through the combined use of the metal EMI lining 104 and the insulating layer 105, it can effectively shield the interference of external electromagnetic waves on the components inside the chassis 1. Since the sensor assembly 202 includes an ammeter, a voltmeter, a wattmeter, a temperature sensor, etc., it can continuously monitor the normal operation of the electrical equipment inside the control cabinet and transmit the data to the controller 401 for the staff to view the operating status of the device.
