Dehumidification integrated system applied to box-type transformer

Abstract

The invention discloses a dehumidification integrated system applied to a box-type transformer and belongs to the field of damp-proof dehumidification of power supply and distribution devices. According to the system, a dehumidification module is arranged in a box-type cabinet body, a temperature sensor and a humidity sensor are correspondingly arranged on an inner part and an outer part of the box-type cabinet body respectively; a drainage pipeline and an exhaust fan are arranged on the cabinet body; the dehumidification module, the temperature sensor, the humidity sensor and the exhaust fanare connected with a local control terminal; and the local control terminal is connected with a remote server through a wireless communication module. Through the system, a drainage-type semiconductorrefrigeration and dehumidification device is adopted in a cooling-drainage-ventilation working mode, a damp environment in the box-type transformer is relieved from the two aspects of dehumidification and cooling, the interior of the box-type transformer is monitored in real time in cooperation with the remote server, the damp-proof dehumidification function in the cabinet body of the box-type transformer is achieved, a great role is played in lowering the probability of a fault of the box-type transformer, safe and stable running of the box-type transformer is ensured, and the service life of the box-type transformer is prolonged. The system can be widely applicable to the damp-proof dehumidification field of the box-type transformer.

Description

technical field [0001] The invention belongs to the field of moisture-proof and dehumidification devices for power supply and distribution devices, and in particular relates to an integrated dehumidification system for box-type transformers for 10 kV box-type transformers. Background technique [0002] In the low-voltage distribution network, box-type substations or box-type transformers (box-type transformers for short) are the most commonly used terminal power distribution methods. They are generally installed outdoors as an intermediate link between high and low voltage conversion and power distribution to residential users. [0003] However, since the box substation and switchgear are often sealed, the internal space is relatively narrow, affected by the rainy season and weather changes, the humid air cannot be discharged in time, and condensation is prone to occur inside. [0004] Condensation attached to components or electrical connection points will affect the insula...

Problems solved by technology

[0008] In the above technical solution, one is to use acetone to clean the insulation of the high-voltage switchgear of the high-voltage switch system, which is usually difficult to implement for a compact box-type transformer, unless the entire box-type transformer is disassembled; and the box-type transformer is disassembled After assembly, it is often difficult to guarantee the assembly quality and electrical safety parameters after assembly in actual work; the second is to use the heating mode to dehumidify, which is not suitable for the high temperature and humid environment in the south
