Problems solved by technology
It is difficult to detect the open circuit fault on the secondary side of the isolation transformer in the status monitoring of the navigation light. The current detection device for the navigation light cannot realize the open circuit fault detection on the secondary side of the transformer.
At present, the navigation light detection device generally shares the secondary winding of the isolation transformer with the navigation light. Once the navigation light detection device fails, it will directly affect the normal operation of the navigation light. In addition, if the secondary side of the isolation transformer is open, the auxiliary It is impossible to monitor the state of the navigation light with the navigation light detection device

A navigation aid lamp isolation transformer open-circuit state monitoring device comprises a principal computer system and transformer state monitoring units. The principal computer system is an industrial control computer, and is arranged in a navigation aid lamp workstation. The transformer state monitoring units are installed in a transformer barrel together with an isolation transformer (the secondary side is composed of a main winding and an auxiliary winding), is used for collecting and transmitting the information of the isolation transformer, and communicate with the principal computer system wirelessly. Through the navigation aid lamp isolation transformer open-circuit state monitoring device and a control method provided by the invention, whether the main winding of the secondary side of the isolation transformer is in an open circuit can be detected effectively, whether there is current in a navigation aid lamp loop can be detected, whether the isolation transformer or the navigation aid lamp fails can be judged and the judgment result can be reported to the principal computer system in real time, so that the problem that the navigation aid lamp loop cannot be handled in a timely manner due to failure of the windings of the isolation transformer is avoided.
Description
technical field [0001] The invention belongs to the technical field of state monitoring of navigation lights, and in particular relates to a monitoring device and a control method for the open circuit state of an isolation transformer of navigation lights. Background technique [0002] The airport navigation light system is a necessary visual aid to ensure the normal takeoff, landing and taxiing of aircraft at night, low visibility and other complex weather conditions. At present, the commonly used airport navigation light system generally uses a series circuit to provide power to the navigation light. In the airport navigation light circuit, the isolation transformer for the navigation light is one of the important components of the power supply and dimming system for the navigation light. 1. Its primary winding is in the series constant current main circuit, and the dimmer is set according to the light levels of the airport navigation light system, and the secondary windin...
