Embodiment 1

[0030] Such as figure 1As shown, a rapid detection device for the mechanical performance of high-voltage circuit breakers based on the Internet of Things includes a chassis and a power supply located in the chassis, and also includes: a time test device for detecting the opening and closing time and bounce time of high-voltage circuit breakers; speed test The device is used to detect the opening and closing speed of the high-voltage circuit breaker; the test device is used to test the operating voltage test and the operating coil current; the control device is used to control the automatic reclosing operation and output the energy storage power supply of the closing motor; the flexible connecting line, It is used for connecting and transmitting signal data; the data line slot 10 is used for connecting flexible connecting lines. It also includes a display screen for displaying data and a memory for storing data, and the display screen is a touch display screen. A printer for p...

Embodiment 2

[0033] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, as Figure 7 As shown, the outer sheath of the cable is provided with a sheath 13, and the sheath is spirally formed by a rectangular elastic strip. The end of the sheath is provided with a connecting ring 14, and the connecting ring is connected with the head body by bolts. A fixing ring 15 protrudes from the head body on the outer wall of the head, and a mounting bolt 16 is installed through the fixing ring.

[0034] A sheath is sheathed on the outer side of the cable. The sheath is made of a spiral elastic strip. The elastic strip has a rectangular strip structure. When the elastic strip is wound in a spiral, there is a certain overlap between two adjacent bending sections. Wrapped in the sheath it surrounds, the sheath is used as the main medium for bearing external forces to enhance the toughness of the cable and prevent the cable from being broken...

Abstract

The invention relates to a testing device, in particular to a device for quickly testing the mechanical property of a high-voltage circuit breaker based on the internet of things. The device for quickly testing the mechanical property of the high-voltage circuit breaker based on the internet of things comprises a machine case, a power supply, a time testing device, a speed testing device, a testing device, a control device, a flexible connection line and a data line slot, wherein the time testing device is used for testing the opening and closing time and the bounce time of the high-voltage circuit breaker; the speed testing device is used for testing the opening and closing speed of the high-voltage circuit breaker; the testing device is used for testing an action voltage test and currentof an operating coil; the control device is used for controlling an automatic reclosing operation and outputting a closing motor energy-storage power supply; the flexible connection line is used forconnecting and transmitting signal data; and the data line slot is used for being connected with the flexible connection line. The device has the beneficial effects that multiple groups of projects can be tested at a time, integrated testing of the mechanical property of the high-voltage circuit breaker can be completed, frequent plugging of a plug is avoided and the testing efficiency is improved.

Description

technical field [0001] The invention relates to a detection device, in particular to a fast detection device for the mechanical performance of a high-voltage circuit breaker based on the Internet of Things. Background technique [0002] High-voltage circuit breakers are relatively common and important equipment in power systems, and the country has relatively strict requirements for dynamic characteristic tests of high-voltage circuit breakers. Carry out electrical preventive tests on site, and tests of high-voltage circuit breakers require frequent operations. In the traditional circuit breaker characteristic test process, there are many test items and a large number of test instruments. For circuit breakers with a voltage level of 35kV and below, the test instruments can be connected to the plug for related tests, but different instruments need to be replaced frequently, and The plug needs to be inserted frequently, the operation is complicated, and centralized testing ca...
