Multifunctional relay protection testing device

Abstract

The invention discloses a multifunctional relay protection testing device, and relates to the technical field of relay protection testing, the multifunctional relay protection testing device comprises a machine body, a movable frame is arranged below the machine body, the outer surface of the machine body is movably sleeved with the movable frame, two moving mechanisms are hinged to the bottom surface of the movable frame, and a pull handle mechanism is arranged on the right side of the machine body. A buffering mechanism is arranged below the machine body, and an adjusting mechanism is arranged below the movable frame and located between the two moving mechanisms. The designed structure is reasonable, the initial compression amount of a buffer spring can be increased through the matched design of a movable frame, an adjusting mechanism, a moving mechanism and a buffer mechanism, the shaking amplitude of a machine body during jolting is reduced, and the problems that the elasticity is reduced along with the increase of the service time of a buffer device, and when the road surface fluctuates too much, the shaking amplitude of the device during movement is large, and components in the device are prone to being damaged are solved.

Description

Technical field [0001] The present invention relates to the field of relay protection testing, and in particular, a multi-function relay protection test device. Background technique [0002] The relay protection test device can test a variety of single relays such as AC current, voltage, intermediate signal, and the entire set of relay protection screens, and test various relays can be tested, and the voltage (current) value is released. , Various contacts (normally open, normally closed, conversion, delayed) are automatically tested three times, automatically calculate the three averages, and print the test results. [0003] The existing relay protection test device generally moves through the staff, when the mobile time is longer, the staff will be more tired, but it will be bumped when the device is moved on the cart, when the pavement undulation At large time, the original inside the device is easily damaged, and therefore proposed - a multi-function relay protection test dev...

AI Technical Summary

Problems solved by technology

[0003] The existing relay protection test device is generally moved by the hands of the staff when moving. When the moving time is long, the staff will be tired, but the device will be bumped when it is placed on the cart. When the value is too large, the original components inside the device are easily damaged, so a multifunctional relay protection testing device is proposed
