Embodiment Construction
[0016] Such as figure 1 Shown is an embodiment of the present invention. The linear and rotary dual-purpose switch test sensor includes a sampling ruler and a sampler. The sampler ruler is a rack 2, and the sampler is composed of an encoder 8 and one end of a gear 4 connected by a shaft 5. The other end of the gear 4 is connected to the coupling 3, and the rack 2 is in transmission connection with the gear 4. A housing 1 is arranged outside the gear 4, wherein the gear 4, the shaft 5, the sliding bearing 6, and the mounting flange 7 are located inside the housing 1, and the gear 4 is connected to the mounting flange 7 of the encoder 8 through the sliding bearing 6.
[0017] Such as figure 2 The shown three-dimensional view of the internal components of the housing, the gear 4 shown is mounted on the shaft 5 through the sliding bearing 6, and the shaft 5 and the encoder 8 are connected through the mounting flange 7; the shaft 5 is mounted on one end of the coupling 3 and connecte...

The invention relates to a sensor for testing a linear rotary dual-purpose switch, comprising a sampling ruler and a sampler, wherein the sampler ruler is a rack; the sampler is formed by coaxially connecting an encoder and one end of a gear; the other end of the gear is connected with a coupling joint; the rack is in transmission connection with the gear; a shell is arranged outside the gear of the sensor for testing the linear rotary dual-purpose switch; and the gear is arranged in the shell and is connected with a middle shaft flange of the encoder by a sliding bearing. Due to use of the sensor for testing the switch, a movable contact is respectively selected to be connected with the rack or the coupling joint according to a linear transmission mode or a rotary transmission mode of the tested high-voltage switch, and different transmission modes do not need to replace the sensor, so that the installation is flexible and fast and the use is convenient.
Description
Technical field [0001] The invention relates to a sensor used on a high-voltage switch action tester, which has a dual-purpose sensor for testing linear rotation displacement. Background technique [0002] The high-voltage switch action characteristic tester is mainly used to test the action characteristics of the high-voltage switch during closing and opening, including the test items related to displacement, stroke, speed, and bounce, and collects the displacement and stroke signals of the moving contact of the high-voltage switch Input into the tester, analyze and calculate the action characteristic of the high-voltage switch, among them the collection of the action characteristic signal of the high-voltage switch is completed by the sensor. [0003] At present, the high-voltage switches used in the domestic power system are in various forms. The moving contact action transmission modes for opening and closing include linear transmission and rotary transmission. When testing dif...
