Problems solved by technology

Relay protectors are often heavy, and users need to carry relay protectors to detect various parts of the power system. It is very tiring to carry relay protectors directly.
However, although a simple support frame with rollers can easily move the relay protector, it cannot freely control the height of the relay protector, and the clamping force is not enough, so that the relay protector is easy to slip down and cause damage

Abstract

The invention provides a relay protector moving frame which comprises a flat base (4), a corrugated pipe (3) perpendicularly arranged at the top of the base (4), and a support bracket (1) perpendicularly arranged at the top of the corrugated pipe (3), wherein four universal wheels (5) in the same size are mounted at the bottom of the base (4); arc springs (2) are symmetrically arranged on inner walls at the two ends of the support bracket (1); splints (6) for clamping a relay protector are arranged on the opposite sides of the two arc springs (2); handles (7) are symmetrically arranged on outer walls at the two ends of the support bracket (1). The relay protector moving frame can tightly clamp the relay protector, facilitates movement of the relay protector, can freely control a height ofthe relay protector and is very simple and convenient to use.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a mobile frame of a relay protector. Background technique [0002] The relay protector mainly uses the change of the electrical quantity of the components in the power system when the short circuit or abnormal condition occurs to form the principle of the relay protection action, as well as other physical quantities, such as a large amount of gas and oil flow accompanying the fault in the transformer tank. Increase in speed or increase in hydraulic strength. In most cases, no matter what kind of physical quantity is reflected, the protective relay includes a measurement part, a logic part, and an execution part. The parameters in the operation of the power system are clearly different between normal operation and fault conditions. The relay protector uses the changes of these parameters to judge the nature and scope of the power system fault on the basis of reflection a...
