Abstract

The invention discloses a filtering-type electric eddy current retarder temperature alarm system based on coupling amplification. The system is characterized in that the system is formed by a signal input circuit, a filtering circuit connected to the signal input circuit, a power supply circuit connected to the filtering circuit, a trigger circuit, a display circuit, a grid coupling amplification circuit and an alarm circuit connected to the display circuit, wherein the trigger circuit, the display circuit and the grid coupling amplification circuit are connected to the power supply circuit respectively; the grid coupling amplification circuit is also connected to the trigger circuit; and the trigger circuit is also connected to the display circuit. In the invention, the grid coupling amplification circuit is arranged and can carry out amplification processing on a temperature signal input into the trigger circuit so that the trigger circuit can well control the alarm circuit; once a working temperature of the eddy current retarder is high, an alarm signal can be timely emitted.

Description

technical field [0001] The invention relates to a temperature alarm system for an eddy current retarder, in particular to a filter type eddy current retarder temperature alarm system based on coupling amplification. Background technique [0002] With the wide application of eddy current retarders in my country's automobile industry, the safety of its use has been paid more and more attention by automobile manufacturers and users. When the eddy current retarder is working, the temperature of the rotor and coil rises rapidly, and the installation position of the eddy current retarder is very close to the oil seal end cover, which can easily cause the fuel tank to catch fire, and then cause a vehicle fire accident, resulting in serious accidents. loss. In order to avoid accidents caused by excessive temperature of the eddy current retarder, it is necessary to design a temperature alarm device to detect the temperature of the main engine of the eddy current retarder. When the t...
