Embodiment approach
[0036] The specific implementation method is as follows: an APP is set in the mobile terminal. Once the cabinet door is opened, an alarm prompt will be issued through the APP. When the battery loses voltage on the input side, it is guaranteed to immediately send a reminder to the platform, and timely alarm through the APP, which is helpful to find the theft of the cabinet or the power failure of the branch.
[0037] The compensation module 3 is modified based on the drawer module of the standard 0.4kV drawer-type low-voltage power distribution switchgear. The drawer-type switchgear is made of steel plate to make a closed shell. A functional module that completes a certain type of power supply task. The functional module is separated from the busbar or cable by a grounded metal plate or a functional plate made of plastic to form three areas: busbar, functional module and cable. Between each functional module There are also isolation measures between the drawers. The main fixed ...
specific Embodiment approach
[0039] The specific implementation method is: when the humid air is sucked by the fan, it flows through a specially designed air duct, and first passes through the semiconductor refrigerator to cool down and condense. outside. After fully circulating dehumidification within the set starting value, the air humidity in the cabinet is reduced to below the dew point, and the entire moisture-proof condensation heating process is completed. At the same time, the signal acquisition sensor of the intelligent dehumidification device is external, which can accurately collect the real humidity in the cabinet in real time, so as to ensure that the intelligent dehumidification device will start dehumidification in advance when the condensation condition is about to be reached in the cabinet. When the temperature in the cabinet is low At the set start value, the dehumidifier starts the internal heater circuit (the heater is connected externally, and the power can be connected to 50~300W), u...
