Problems solved by technology

Regardless of whether it is an AC contactor or a DC contactor, its control coil is basically excited by DC current. The life of the AC electromagnet will be relatively short, and it is prone to vibration, which is not conducive to the reliability of the contact.
[0003] In the process of designing the auxiliary contact of the contactor, it is often encountered that the auxiliary contact space layout is difficult, the auxiliary contact synchronization time exceeds the standard, the auxiliary contact synchronization time is difficult to adjust or cannot be adjusted, and the cause of the pull-in time is not synchronized. It is the inconsistent length of motion stroke, because the internal contact gap of each micro switch is different

Abstract

The invention provides a device for adjusting synchronization time of multipath auxiliary contacts of a contactor and a use method thereof. The device comprises contactor auxiliary contacts. The contactor auxiliary contact is provided with a circuit board, a micro switch, a push plate and a push rod, and a spindle. The micro switch is between the circuit board and the push plate. The spindle is ona center line of the circuit board and the push plate. The circuit board is mounted on one end of the spindle. The micro switch is installed below the circuit board. The device can solve a problem ofdifficulty in spatial layout of the auxiliary contacts of the contactor, and also can adjust the synchronization time of the auxiliary contacts of the contactor, thereby greatly improving performanceand working reliability of the contactor, and effectively preventing dangerous events caused by synchronization time deviation of the auxiliary contacts of the contactor. Thus, range of application of the contactor is wider, and use is safer.

Description

technical field [0001] The invention belongs to the technical field of aviation devices, and in particular relates to a device for adjusting the synchronization time of multiple auxiliary contacts of a contactor and a method for using the same. Background technique [0002] A contactor is an automatic control switch used to remotely control the on-off of AC and DC main circuits or large-capacity circuits. It has the functions of controlling high voltage with low voltage and controlling high current with low current. It is called an aviation contactor when it is used in aviation conditions. It can be installed away from the driver, and the driver can control its coil mechanism by manipulating the switch installed in the cockpit to achieve the purpose of controlling the electrical circuit. Whether it is an AC contactor or a DC contactor, its control coil basically uses DC excitation, and the life of the AC electromagnet is relatively short, which is prone to vibration, which i...
