Electronic centrifugal switch and test method thereof

Abstract

The invention relates to an electronic centrifugal switch and a test method thereof which are designed to solve the technical problem that the structure design and test method of existing homogeneous products are not good. The main points of the electronic centrifugal switch and the test method provided by the invention are as follows: the body of an electronic centrifugal switch is provided within a circuit board, a built-in micro-computer and a controlled silicon and the other elements; one lateral side of the body is respectively provided with a first wiring end, a second wiring end and a third wiring end; the first wiring end is connected with a starting capacitor CS, the second terminal end is connected with a starting winding S; and the third wiring end is connected with a main winding M and the starting winding S of a motor. The test method comprises the following steps of: connecting the electronic centrifugal switch with a power supply, firstly reading a supply voltage and a frequency, identifying the frequency of the motor as 50 Hz or 60 Hz, and then testing poles of the motor, and finally controlling the motor according to the corresponding motor frequency and poles. The electronic centrifugal switch is convenient in use and installation, and the test method is feasible, so that the electronic centrifugal switch and the test method are applied to controlling a single-phase capacitive start motor (YC), a single-phase capacitive start and operating motor (YL).

Description

technical field [0001] The invention relates to an electronic centrifugal switch, in particular to an electronic centrifugal switch and a testing method thereof. Background technique [0002] The existing centrifugal switch generally refers to a mechanical centrifugal switch, which is mainly used to control the starting coil of a single-phase motor, and it generally consists of two parts: 1. A centrifugal mechanism that rotates around the motor shaft; 2. A fixed switch with an electrical contact device , used to control the start coil. For example, the patent No. ZL200720007071.X published in the Chinese patent literature, the date of authorization announcement was March 19, 2008, and the name of the utility model is "a kind of motor centrifugal switch"; Positioning sleeve, a sliding sleeve that is set on the positioning sleeve and can be used as an axial sliding opening and closing start switch. One end is slidably guided by the guide plate of the positioning sleeve, and t...
