Test table for general-engine break-over device

Abstract

The invention discloses a test table for a general-engine break-over device, wherein an input end of an inductance coil is connected to a mains supply via a first capacitor; an output end is connected to an input end of an output indication circuit; the output indication circuit comprises an igniter; the igniter is connected to an output end of the inductance coil; a first output end of the igniter is taken as a first testing end which is used for ignition testing of the to-be-tested break-over device; a second output end is connected with a reverse voltage-stabilizing diode in series and then connected to a public ground end; the second output end and the reverse voltage-stabilizing diode are led out from the public ground end and taken as a second testing end and a third testing end; when the first testing end, the second testing end and the third testing end are connected to the tested break-over device, the second output end outputs a low level, a control circuit controls a timer to record time; and on the contrary, the second output end outputs a high level, and the control circuit controls the timer to be reset. The test table for the general-engine break-over device has the advantages that a large-power motor and a flywheel are eliminated during testing, and thus energy consumption is reduced; automatic and accurate time recording is realized; and product quality is improved.

Description

technical field [0001] The invention relates to the field of mechanical testing, in particular to a test bench for a through-machine conductor. Background technique [0002] The performance of the through-machine lead-through needs to be tested during the manufacturing process, and the traditional detection method is to use a high-power motor to drive the flywheel to rotate for testing. This detection method has several disadvantages: on the one hand, it consumes a large amount of electric energy due to the use of a high-power motor; on the other hand, because the start and control of the timing system is manually controlled by a switch, and the timing system cannot stop timing after the delay is terminated. , resulting in inaccurate timing, misjudgment of faults, and seriously affecting product quality. Contents of the invention [0003] The object of the present invention is to provide a test bench for a through-machine conductor, which reduces the energy consumption of...
