At present, in various buildings, such as public buildings, hotels, office buildings, factories and the like, the control cabinets of cold and heat source energy-saving control systems increasingly see the application of strong current control (380VAC) + weak current control (24VAC) in an integrated manner, namely, the strong current control and the weak current control are integrated into a strong current and weak current integrated control cabinet in a cabinet body. The success of such application depends mainly on the interference problem of strong and weak current that can be handled. Because the existing strong and weak current integrated control cabinet mostly simply adopts the partition board to separate the strong and weak current control parts, the weak current control part lacks the anti-interference capability, so the analog signals (such as frequency converter control and feedback, temperature, humidity monitoring and the like) of the weak current part in partial engineering projects are often interfered by the electromagnetic wave of strong current (380VAC), the analog signal deviation collected by the weak current integrated control cabinet is large, the analog control signals output by the weak current controller are inaccurate, and the control failure of the weak current part is easily caused. In addition, the cables of the strong current control part and the weak current control part of the existing strong current and weak current integrated control cabinet are crossed, so that the interference of strong current electromagnetic waves on weak current control is further aggravated, the wiring complexity is increased, and the follow-up maintenance operation is not facilitated.
