Airplane direct current appliance function detector

Abstract

The invention provides an airplane direct current appliance function detector which can be used for detecting online (not leave the position) to eliminate the labor intensity of plane workers and to shorten fault locating time or periodical inspection for an airborne equipment electrical performance. The technical scheme of the airplane direct current appliance function detector comprises a power socket. The front end of the power socket is connected with the front end of a power switch through a power circuit breaker. The front end of the voltage indicator, the front end of the current indicator, the front end of the timer and the front end of the power light are respectively connected with the back end of the power switch. The back end of the current indicator is connected with a detective button. The back end of the timer and a three-position change-over switch are respectively connected with the detective button through a detective circuit breaker. An opening signal light and the front end of the electric movable valve loading are respectively connected with one road of the three-position change-over switch through a testing socket. A full opening signal light is connected with the back end of the electric movable valve loading.

Description

technical field [0001] The invention belongs to aviation auxiliary equipment and relates to an aircraft DC equipment function detector. Background technique [0002] In daily maintenance work, when there is often doubt about the reliability of the internal DC equipment of a certain system (such as electric mechanism, electric valve, etc.), traditional troubleshooting methods can only be used for simple measurements (such as access, open , resistance, grounding, etc.), but it is impossible to check the situation such as: the sticking of the electric mechanism, the state of the control circuit after being connected. This requires an in-depth investigation after the DC equipment is powered on independently, otherwise, the equipment needs to be disassembled for in-field calibration or return to the factory for inspection and verification, which will cause certain difficulties in quickly locating the fault, and the work efficiency is extremely low; During periodic work, it is re...

Problems solved by technology

[0002] In daily maintenance work, when there is often doubt about the reliability of the internal DC equipment of a certain system (such as electric mechanism, electric valve, etc.), traditional troubleshooting methods can only be used for simple measurements (such as access, open , resistance, grounding, etc.), but cannot check the situation such as: the sticking of the electric mechanism, the state of the control circuit after switching on, etc.

This requires an in-depth investigation after the DC equipment is powered on independently. Otherwise, the equipment needs to be disassembled for in-field calibration or return to the factory for inspection and verification, which will cause certain difficulties in quickly locating the fault, and the work efficiency is extremely low; During periodic work, it is required to perform performance testing on independent equipment such as the electric mechanism, such as checking the opening and closing of the electric mechanism, and checking whether the time of the working stroke meets the technical requirements

However, there is no such special testing equipment in the current outfield maintenance work of the aircraft, which causes certain difficulties to the maintenance work of the aircraft
