Description

Technical Field

[0001] The invention relates to the technical field of a heating tape control box, and in particular to a heating tape control box and a control method thereof. Background Art

[0002] Electric heating cables are generally used for heating and heat preservation of pipelines, containers and tanks in industries such as civil solar energy, floor heating, fire protection, petroleum, chemical, steel, and electric power. In addition to these, electric heating cables can also be used in snow melting and plant cultivation. As a flat belt-shaped heating element composed of a conductor, an insulating layer, a shielding layer and a sheath layer, the electric heating cable mainly operates by converting electrical energy into thermal energy after connecting to a power source to compensate for the heat loss of the heated body. Among them, when the heating cables are used in an integrated manner, a control box is required to control a large number of heating cables in the same way.

[0003] However, the existing heating tape control box still has certain problems in actual use. During use, the existing heating tape control box integrates and controls a large number of heating tapes, resulting in a large number of control devices in the box. During long-term operation, some devices will operate at high load, resulting in high temperature heating. High temperature heating is difficult to find through ordinary maintenance and detection. Therefore, the operator cannot check the heating point at the first time, thereby increasing the difficulty of detection and maintenance. At the same time, it is difficult for the existing heating tape control cabinet to shut down the circuit of the electronic control device in different heating parts, so that the electronic control device in the heating part continues to run under high temperature load, which can easily cause fire hazards. Summary of the invention
