Problems solved by technology

[0003] Because there are multiple trip switches in a certain area, the installation space is small, and they are connected in parallel with the detection equipment, so it is very tedious and time-consuming to use the traditional dichotomy method to measure the resistance to locate the faulty trip switch.

Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the examples.

[0038] Such as Figure 1a , 1b As shown, contact 1: power supply; contact 2: electrical equipment; contact 3: auxiliary contact (for monitoring); contact 4: auxiliary contact (for monitoring). Figure 1a Indicates that the jumper switch is closed, that is, the power supply contact is closed and the monitoring contact is open; Figure 1b Indicates that the trip switch has jumped out, that is, the power supply contact is open and the monitoring contact is closed.

[0039] Such as figure 2 As shown, the on-board monitoring equipment is connected to the red wire, and the auxiliary contacts 3 of all the monitored jumpers are connected to the red wire; the blue wire is connected to the ground point of the aircraft, and the auxiliary contacts 4 of all the monitored jumpers are connected to to the blue wire. Under normal circumstances, there is an open circuit between the mon...

Abstract

The invention relates to a rapid positioning method for civil aircraft false circuit breaker jump. The rapid positioning method comprises the steps that a digital ammeter, a power supply device and a circuit breaker are connected, and circuit breaker jump positioning is conducted according to the value of the ammeter. According to the rapid positioning method for civil aircraft false circuit breaker jump, the fault removing time can be substantially shortened, the working efficiency is greatly improved, and capital is greatly saved; when positioning is conducted through the method, a wire of an auxiliary contact of the circuit breaker does not need to be disconnected, what is needed is only to enable the circuit breaker to be turned on and off manually and read the readings of the ammeter, and the fault point can be precisely positioned through size comparison of the readings; and the row where the fault circuit breaker is located can be soon found out through row positioning and simple current value measuring, the positioning range is narrowed, and the positioning speed is increased.

Description

technical field [0001] The invention relates to a method for determining the position of a trip switch of an aircraft failure, in particular to a rapid positioning method for a false trip switch jumping out of a civil aviation airliner. Background technique [0002] At present, the main model of the world's civil aviation transportation is a single-aisle type (for example: the A320 series of Airbus Corporation). This type of civil aviation airliner has a warning function of "an abnormal state of jumping out of a jump switch in a certain area", which is used to prompt the pilot to quickly locate the relevant area and confirm the working status of the relevant system. When the warning message of tripping out of the trip switch appears on the aircraft, the flight crew or maintenance personnel check but no real tripping out of the tripping switch is found, we call it a "false tripping out" state. This false status information is distracting to the pilot and should therefore be ...
