The internal layout of the terminal box is facilitated, and the problem that the cable is damaged by baking in the terminal box due to too high temperature of the existing heater is solved.
The product mainly solves the problem that the terminal box heater 1 is uneven in heating. 2. Too close to the leads tends to burn out the circuit. 3. The heating adjustment is not intelligent.
This product heating device is in terminal bottom of the case portion, and the material is graphite alkene film that generates heat, and the structure is multilayer partial shipment structure.
Is divided into three layers.
The upper surface layer is a thin aluminum plate with good thermal conductivity and corrosion resistance.
The middle layer is a graphene or carbon fiber heating film.
The lower layer is made of heat-insulating and insulating material.
The temperature controller is connected with the heating device, and the temperature detector and the humidity detector are added to adjust the temperature and humidity inside the box body. The adjustment is carried out in a manual mode and an automatic mode. And multi-gear stepless regulation and control can be realized.
After the application runs secretly for a period of time, the feedback of field technicians has the advantages that:
large heating area, no danger at low temperature, long service life and no maintenance. And an intelligent temperature control device is added, so that the temperature can be adjusted according to the ambient temperature and the humidity. The temperature in the terminal box is kept in a proper range by dispelling damp at low temperature in summer and intelligently heating in winter. The internal layout of the terminal box is facilitated, and the problem that the cable is damaged by baking in the terminal box due to too high temperature of the existing heater is solved.
