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 design 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 machine body is damaged are solved. And the shaking amplitude of the device during movement is large, and original parts in the device are prone to being damaged are solved.

Description

technical field [0001] The invention relates to the technical field of relay protection testing, in particular to a multifunctional relay protection testing device. Background technique [0002] The relay protection test device can test a variety of single relays such as various AC and DC currents, voltages, intermediate signals, and the entire group of relay protection screens, and can test the pull-in voltage (current) value and release voltage (current) value of various relays , The pull-in time and disconnection time of various contacts (normally open, normally closed, conversion, delay) are automatically tested three times, the average value of the three times is automatically calculated, and the test results can be printed. [0003] The existing relay protection test device is generally moved by the staff when moving. When the moving time is long, the staff will be tired, but when the device is moved on the cart, it will be bumped. When the size is large, the original...

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
