The high-voltage switch comprehensive tester is equipped with three types of speed sensors, which are used in different situations. The three kinds of sensors are connected to the "speed sensor" socket of the instrument through a sensor signal line.

1. General-purpose speed sensor (acceleration sensor)

Traditional speed sensors usually use sliding wire resistors or photoelectric sensors (divided into two types of grating and photoelectric encoder), these types are composed of two parts of motion and static. When measuring the speed, they are installed on the moving parts (moving contacts or lifting rods) and stationary parts (general cap holders or switch bases) of the switch, and they should cooperate well. In this way, many different mounting brackets need to be made for different switches, and it is difficult to install and disassemble on site.

After years of research, the company has applied acceleration technology to switch speed measurement, solving the technical problems of difficult installation, coordination, and testing of the speed measurement sensor on the switch site. The general sensor is convenient, simple and easy to operate on site.

Note: Install the universal sensor directly on the lifting rod of the switch or on the horizontal connecting shaft, or on other transmission rods.

2. Installation note 1: The socket direction of the universal sensor is the same as the moving direction of the Dongxuan, try to keep it parallel to the Dongxuan, if it is installed skewed, the measurement data may be inaccurate.

3. Installation note 2: The general sensor installation should be selected according to the thickness of the moving rod. The clamps of the corresponding radius make the sensor very firmly stuck on the moving rod without shaking. When the switch is in action, the sensor should be tightly supported by the moving rod to move together, and there must be no relative shaking between the moving rod, otherwise the test data may be inaccurate.

4. Installation note 3: The universal sensor is installed on the switch rod. When the switch is activated, there should be a certain position space for the sensor up, down, left and right, so as not to cause the sensor to collide with the surrounding switch parts during the movement and cause damage.
