Abstract

The invention provides an electronic centrifugal switch detection device. The technical problem that the existing electronic centrifugal switch detection means is complex and low in detection precision is solved. The electronic centrifugal switch detection device has a shell. An ampere meter, a start button and a stop button are arranged on the surface of the shell. An external power interface, amotor cable interface and a motor power interface are led out of the shell. A detection circuit is arranged in shell, and the detection circuit is electrically connected with an electronic centrifugalswitch. The detection circuit comprises an operation relay, a brake relay and a time relay. The operation relay is connected in series with a normally closed contact of the brake relay, and is connected in series with a normally open contact of the start button and a normally closed contact of the stop button. The brake relay is connected in series with a normally closed contact of the operationrelay and a contact of the time relay, and is connected in series with a normally closed contact of the start button and a normally open contact of the stop button. The electronic centrifugal switch detection device can be widely applied to the technical field of centrifugal switch test.

Description

technical field [0001] The invention relates to the technical field of centrifugal switch testing, in particular to an electronic centrifugal switch testing device. Background technique [0002] A grinder is a common equipment used to grind various knives and tools. It is mainly composed of a base, a grinding wheel, a motor or other power sources, a bracket, a protective cover, and a water feeder; the capacitor-started grinder motor is usually Single-phase asynchronous motors, single-phase asynchronous motors YL YU YC series, motor starting needs to use a large-capacity starting capacitor, and this capacitor can not participate in the operation for a long time, so it is necessary to use an electronic centrifugal switch to control on-off, the electronic centrifugal switch needs to be connected with the starting Capacitors and motor auxiliary windings are used in series, and the quality of the electronic centrifugal switch directly affects the quality of the motor. At present,...
