Description

Technical Field

[0001] The present invention relates to the technical field of remote operation and maintenance equipment, and in particular to a remote operation and maintenance device for a relay protection device. Background Art

[0002] Relay protection devices play a detection and protection role in the power system. When electronic components in the power system, such as motors and lines, or the power itself, fail and endanger the safe operation of the power system, they can promptly send warning signals to the operating personnel on duty, or directly send a trip command to the controlled circuit breaker to terminate the operation of the equipment. However, when a power system fails, the staff needs more time to troubleshoot and repair it. In order to save the staff's working time and to troubleshoot the power system more quickly, remote operation and maintenance devices will be installed to troubleshoot and detect it.

[0003] Remote operation and maintenance devices eliminate the limitations of physical distance, greatly saving the time technicians need to troubleshoot and repair power system faults, and saving the high costs caused by the need for technicians to be stationed or checked.

[0004] As for the installation of remote operation and maintenance devices, some small enterprises will directly expose the remote operation and maintenance devices to the outside world, or place the remote operation and maintenance devices in an installation box and protect them to a certain extent through the installation box. However, in order for the remote operation and maintenance device to better use the installation box, or to better fix the remote operation and maintenance device in the installation box, the internal diameter of the installation box is generally corresponding to the outer diameter of the remote operation and maintenance device, so that the space between the remote operation and maintenance device and the inner wall of the installation box is smaller. In this case, the heat dissipation performance of the remote operation and maintenance device will be affected to a certain extent. Therefore, heat dissipation openings will be opened on the remote operation and maintenance device and the installation box, and heat dissipation will be blown into the installation box and the remote operation and maintenance device by a cooling fan. However, the space between the installation box and the remote operation and maintenance device is small, and the gas flow speed is slow, which in turn affects the heat dissipation performance.
