Embodiment Construction
[0012] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.
[0013] Such as figure 1 Shown is the structural diagram of the embodiment of the dual-channel resolver open-circuit rapid test equipment embodiment of the present invention, as can be seen from the figure, the test equipment includes two test displays L1 and L2, and L1 and L2 all include test connection terminals J1 and J2, L1 and L2 They are respectively used to connect with the four terminals X1~X4 of the excitation channel of the transformer to be tested to form an excitation test circuit. Among them, the colors of X1 and X4 are the same, and the colors of X2 and X3 are the same; L1 and L2 are also used to connect with the transformer to be tested. Two sets of four-color terminals Y1~Y8 of the fine machine channel and the rough machine channel are connected to form a rough and fine machine test circuit; among them, the colors of Y1 and Y2 a...

The invention discloses a piece of dual-channel rotary transformer open circuit quick-test equipment comprising two test displays L1 and L2. L1 and L2 respectively include two test connection terminals. L1 and L2 are respectively used for being connected with four wiring terminals of an excitation channel of a to-be-tested transformer to form an excitation test circuit. L1 and L2 are further respectively used for being connected with two channels of wiring terminals Y1-Y8 in four colors of a fine machine channel and a coarse machine channel of the to-be-tested transformer to form a fine and coarse machine test circuit. The excitation test circuit and the fine and coarse machine test circuit adopt switching circuits to carry out switching control, the first switching circuit controls open circuit test of the excitation channel of the dual-channel rotary transformer, and the second switching circuit controls open circuit test of the fine machine channel and the coarse machine channel of the dual-channel rotary transformer. By adopting the test equipment, operation is simple and accurate, and detection is quick and efficient. Whether an open circuit exists in the excitation channel and the fine and coarse machine channels of a tested dual-channel rotary transformer can be distinguished by testing the states of the displays in the process of switch flipping.
Description
technical field [0001] The invention belongs to the technical field of electronic detection devices, and relates to a rapid open-circuit test device for a dual-channel rotary transformer. Background technique [0002] The resolver is used in the motion servo control system. It is a precise angle, position, and speed detection device. It has the characteristics of high sensitivity and strong anti-interference ability. It is especially suitable for environmental conditions such as high temperature, severe cold, humidity, high speed, and high vibration. bad occasions. In order to meet the requirements of a higher-precision synchronous system, in recent years, an electrical variable-speed dual-channel measurement system composed of a dual-channel resolver has appeared. The dual-channel resolver is a combination of two resolvers with unequal pole pairs. Usually, those with few extreme logarithms are called rough machines, while those with many extremely logarithms are called fin...
