Embodiment approach

[0060] When the shockproof platform 5 of the protection tester is in a stable state, the transmission line 205 is not affected by the force of the stepping motor 11, and the balance mechanism 2 tightens the brake line 204 by the elastic force of the return spring 202, so that the friction force between the friction plates 201 reaches the maximum value, when the car body drives the anti-vibration platform 5 of the protection tester with an inclination angle, according to the difference of the angle, when the transmission line 205 is subjected to the effect of the stepper motor 11 force, the return spring 202 is compressed by the lock bar 203, and the brake line 204 is loosened to reduce The effect of friction can ensure that the multifunctional test platform for relay protection test can move flexibly by self-help obstacle surmounting, climbing stairs, etc. in a stable and bump-free state. The specific implementation method is as follows:

Abstract

The invention discloses a multifunctional testing platform and method for relay protection testing. A chassis and caterpillar tracks are connected by rubber vibration isolators. Bearings are used to connect a tester protecting shockproof platform and tripods which are fixed on the chassis. A control module adjusts the friction force by controlling a stepping motor so that a testing platform is stabilized in the same horizontal plane. Meanwhile, the revolution speed of the caterpillar track is controlled through controlling a DC motor to keep stable operation of a device. An ultrasonic sensor is arranged in an electrified region, which is isolated to ensure the safety of testers. A power module is powered by a battery. The power module has two circuits, one of which supplies power to the platform in a DC-DC manner, and the other one of which supplies power to a tester for testing in a DC-AC manner. In transformation station on-site protection testing, a tester is heavy and is hard to move around easily by people especially in an on-site environment with stories. The testing platform enables a high-precision on-site relay protection tester of a transformation station to easily accomplish movements such as automatic obstacle crossing and stair climbing while keeping steady without any bumpiness.

Description

technical field [0001] The invention relates to a debugging platform, in particular to a multifunctional testing platform and a method thereof for relay protection tests. Background technique [0002] Microcomputer relay protection testing device has been widely used in the debugging of intelligent substations. However, there are many problems in the practice of on-site debugging that are worth studying and improving. For example, the relay protection test device usually used for on-site debugging weighs 30-40Kg, and it mainly relies on manpower to carry the test equipment, including moving inside the substation, loading and unloading trucks, going up and down stairs, etc., which is not only time-consuming and labor-intensive, but also brings a lot of trouble to the testers. It is very inconvenient; in addition, because there is no suitable platform to support the test device during on-site commissioning, the tester can only place the test equipment on the ground for operati...
