Abstract

The invention discloses a relay protection fixed value setting simulation machine. The relay protection fixed value setting simulation machine comprises an external rack and a shell; wherein the external rack is composed of a piston, a sucker, positioners, a telescopic rod and a back belt; the telescopic rod is arranged on a side end wall inside the external rack, and the top of the telescopic rodis provided with the piston; the upper and lower sides of the telescopic rod are provided with the positioners, and the positioners are fixed on the end wall of the external rack; the shell is connected with the external rack by lock catches, and the external rack is distributed on both sides of the shell; the upper surface of the shell is fixed with a touch display screen; a charging interface is arranged on one side of the lower end of the shell, a USB interface is arranged on the other side of the lower end of the shell, and both the USB interface and the charging interface are arranged onthe lower end wall of the shell; and the inner upper end of the shell is provided with a PID controller. The relay protection fixed value setting simulation machine has the advantages of simple operation and convenient use, and has the use values of fixed value setting, fixed value training and fixed value reference, which strengthens relay maintenance and saves human and material resources.

Description

technical field [0001] The invention relates to the field of relay setting technology, in particular to a relay protection setting simulation machine. Background technique [0002] The relay protector is a comprehensive relay protection device based on microprocessor design, which integrates inverse time (Inverse Time) and definite time (Independent Time) relay protection. Protective relays are often used to provide safety protection for electrical equipment, such as short-circuit and ground fault protection for transformers, motors, generators, and transmission lines in power distribution systems. In order to prevent the occurrence of wrong setting in the process of on-site setting and improve the success rate of setting of relay protection device, a kind of simulation machine for setting value of relay protection is specially introduced for people to diagnose and use. Contents of the invention [0003] The purpose of the present invention is to provide a relay protectio...
