Abstract

The invention is suitable for the technical field of railway communication, and provides tuning equipment. The tuning equipment comprises a first interface, a first inductor, a first capacitor and a second interface, the first interface is connected with a first end of the first inductor through a first connecting line, a second end of the first inductor is connected with a first end of the first capacitor through a second connecting line, a second end of the first capacitor is connected with the second interface through a third connecting line, and the first interface and the second interface are used for connecting an external circuit; wherein at least one of the first connecting line, the second connecting line and the third connecting line is a manganese copper wire. According to the tuning equipment, the manganese copper wire is used as the connecting wire of the tuning equipment, the resistance temperature coefficient of the manganese copper wire is low, the resistivity is high, and the resistance compensation of the resonant circuit can be realized by using the short manganese copper wire, so that the manganese copper wire is not easy to deform, the resistance value change in the working process is small, and the stability of the tuning equipment can be improved.

Description

technical field [0001] The invention belongs to the technical field of railway communication, and in particular relates to a tuning device. Background technique [0002] Tuning equipment is an important outdoor equipment in the non-insulated track circuit system, which is mainly used to realize electrical insulation adjustment in the outdoor tuning area. The working nature of the tuning equipment makes the tuning equipment need to have high precision. The production process needs to be debugged many times to ensure the performance of the tuning equipment. [0003] However, the tuning process of the tuning equipment is usually carried out at room temperature. Even if the tuning equipment is qualified, the parameters of the tuning equipment may be greatly affected by the ambient temperature when it is put into use, and it is difficult to ensure the tuning accuracy. Contents of the invention [0004] In view of this, an embodiment of the present invention provides a tuning ...
