The invention discloses a device for internally controlling the humidity of a switch machine, comprising a main control board, a dehumidifier shell, an air inlet fan, an air outlet fan and a condenser, wherein the air inlet fan, the air outlet fan and the condenser are arranged in the dehumidifier shell; the air inlet fan is connected with the switch machine through the air inlet pipe, the air outlet fan is connected with the switch machine through the air outlet pipe, and the condenser is arranged between the air inlet fan and the air outlet fan. A sensor is arranged in the shell of the dehumidifier, the sensor comprises a temperature sensor and a humidity sensor, and the main control board is respectively connected with the temperature sensor and the humidity sensor through a signal line. The device adopts modular design, and the components are installed outside the switch machine, which is convenient to disassemble, assemble and replace, avoiding the problem that the switch machinecannot be universal because of the narrow and short internal space of the switch machine, and avoiding the normal operation of the switch machine being affected by the device problems.
Description
technical field [0001] The invention relates to the field of railway signal equipment, in particular to a device for internally controlling the humidity of a switch machine. Background technique [0002] The switch machines operated online by domestic road bureaus have problems such as water and humidity easily entering the switch machines, causing rust and jamming of mechanical parts, oxidation of switch contacts and electrical contacts, poor contact, etc., affecting driving safety and transportation efficiency. At present, on-site equipment maintenance personnel can only manually remove the accumulated water in the switch machine and place a desiccant against the humidity. However, the desiccant has a limited degree of moisture absorption and cannot be used for a long time. These problems have been criticized for many years. Cause the accident that affects driving safety, form serious potential safety hazard. Under the rapid construction pace of speed increase, high-spee...
