Description

Technical Field

[0001] The utility model relates to the technical field of fault recording devices, in particular to an improved fault recording device. Background Art

[0002] Fault recording devices play a very important role in ensuring the safe operation of power systems. When a fault occurs in the power grid, the installed fault recording device can record the waveform and effective value of the three-phase current and zero-sequence current on the line during the entire process of the fault, and the waveform and effective value of the three-phase voltage and zero-sequence voltage on the busbar, and form a fault analysis report, giving the fault type of this fault, and can check the amplitude and phase of the current and voltage, the action time of the protection on this side, and the time when the high-frequency protection transceiver on both sides of the line sends and stops sending, the circuit breaker opening and closing time, etc.

[0003] For example, the public document CN219142997U discloses a novel fault recording device, comprising a recording device body, a terminal block body being fixedly connected to one side of the recording device body, and universal wheels being movably connected to the four sides of the back of the recording device body. The utility model provides a recording device body, a terminal block body, universal wheels, a protective frame and an anti-static fan. The protective frame provides basic protection for the terminal block body to prevent the impurities and dust in the external environment from polluting the terminal block body during the carrying process of the recording device body, thereby affecting the normal use of the recording device body. The anti-static fan performs anti-static blowing operation on the inner cavity of the protective frame to reduce the influence of static electricity on the terminal block body and the recording device body when used with external connection equipment, and at the same time increase the heat dissipation function of the inner cavity of the protective frame, thereby solving the problem that when the portable device is connected to other electrical equipment, dust and static electricity easily interfere with the device due to the lack of good protection of the connection interface.

[0004] The above device can protect the wiring port when the device is carried, but the retracting plate needs to be opened when the wire is plugged in to complete the wiring purpose. In this case, the wiring port cannot be protected from dust, and some unplugged connectors are more susceptible to dust. Utility Model Content
