Technical Field
The invention relates to the field of cable laying equipment, in particular to a condensation-proof cable branch box.
Background
A cable distribution box is an apparatus for performing distribution, branching, splicing and conversion circuits on cable lines, and is mostly used outdoors.
Cable distribution boxes are divided into two main categories according to their electrical composition: one type of the cable distribution box does not contain any switch equipment, only accessories for processing and connecting cable ends are arranged in the box body, the structure is simpler, the size is smaller, the function is single, and the cable distribution box can be called as a common distribution box; the other type is that the box not only has accessories of a common tapping box, but also contains one or more switching devices, and the box has the advantages of complex structure, large volume, more connecting devices, large manufacturing technical difficulty and high manufacturing cost, and can be called as a high-grade tapping box.
The cable distribution box is generally installed outdoors, and condensation is easily generated when wet weather is met, so that the cable distribution box is damaged, the service life is shortened, the cable in the cable distribution box is influenced, and the possibility of electrical short circuit is provided.
At present, the mode of removing condensation of a cable distribution box on the market mainly comprises two modes of adding an air exchange fan and a temperature and humidity controller, wherein an exhaust fan is connected with a temperature sensor and a humidity sensor; the exhaust fan can increase the water evaporation in the cable tapping box, effectively prevent the water collection condensation phenomenon and effectively prevent the moisture in the cable tapping box; the exhaust fan is controlled by a temperature sensor and a humidity sensor, when the temperature or the humidity reaches a set value, the exhaust fan is automatically started to exhaust air outwards so as to reduce the temperature or the humidity, and when the temperature and the humidity are reduced to the set value, the exhaust fan is automatically powered off and stopped. However, the condensation removing device cannot fundamentally inhibit the generation of condensation, additional resources are required to be consumed in the condensation removing process, the device is not environment-friendly enough, most of the devices are not provided with power supplies on the site, and the cable distribution box is inconvenient to install the condensation removing device.
Disclosure of Invention
