Description

Technical Field

[0001] The utility model relates to the technical field of fault recorders, in particular to a fault recorder with a protective device. Background Art

[0002] Fault recorders are used in power systems. When a fault occurs in the system, they can automatically and accurately record the changes in various electrical quantities before and after the fault. The analysis and comparison of these electrical quantities are important for analyzing and handling accidents, judging whether the protection is operating correctly, and improving the safe operation level of the power system. Fault recorders are important automatic devices for improving the safe operation of power systems. When a fault or oscillation occurs in the power system, it can automatically record the changes in various electrical quantities during the entire fault process.

[0003] Most of the existing fault recorders do not have a protective structure at their outer ends. After the fault recorder is placed inside a box for protection, when the box falls, it is still inconvenient to protect the fault recorder body from multiple angles during the fall. For this reason, we propose a fault recorder with a protective device. Utility Model Content

The fault recorder body 100 includes a display screen 101 and a jack 102 respectively arranged on both sides of its front end, and a lifting rod 103 movably installed at the center of the fault recorder body 100. The protective assembly 200 includes corner protection blocks 201 movably mounted at the four corners of the fault recorder body 100, and side buffer strips 202 and side buffer sheets 203 movably mounted on the outer side and the upper and lower ends of the corner protection block 201. A plurality of A plurality of horizontal restraint holes 204 are formed, and horizontal movable columns 205 are movably installed in the horizontal restraint holes 204, and the outer ends of the horizontal movable columns 205 are fixedly connected to the edge buffer strips 202. The horizontal restraint holes 204 at the inner ends of the horizontal movable columns 205 are also movably installed with first buffer springs 206. The protection component 200 also includes vertical restraint holes 207 provided at the upper and lower ends of the corner protection block 201, and vertical movable columns 208 movably installed in the vertical restraint holes 207, and the outer ends of the vertical movable columns 208 are fixedly connected to the edge buffer strips 203. The protection component 200 also includes second buffer springs 209 movably installed in the vertical restraint holes 207 at the inner ends of the vertical movable columns 208.

[0028] Specifically, the fault recorder is used in the power system. When a fault occurs in the system, it can automatically and accurately record the changes in various electrical quantities before and after the fault. The analysis and comparison of these electrical quantities play an important role in analyzing and handling accidents, judging whether the protection is operating correctly, and improving the safe operation level of the power system.
