The invention relates to the technical field of high-voltage test safety protection and provides a high-voltage electrical test protection system. The system comprises a host, an encircling net locking device, a remote controller and a grounding line test device. The encircling net locking device is used for determining whether an encircling net is installed or not, and sending a first wireless signal to the host when determining that the encircling net is installed. The remote controller is used for determining whether wire connection is finished or not, and sending a second wireless signal to the host when determining that the wire connection is finished. The grounding line test device is used for testing whether a grounding line is grounded well and sending a third signal to the host when testing that the grounding line is grounded well. Multiple indication lamps are arranged on the host. The host receives the wireless signal about the installation of the encircling net, the wireless signal about the finishing of wire connection and the wireless signal about well finishing of the wire connection. The indication lamps are turned on simultaneously, and the host executes test voltage rising operation. According to the invention, a safety protection problem in case of all kinds of dangerous points or easy ignoring operation in electrical test work can be solved.
Description
technical field [0001] The invention belongs to the technical field of high-voltage test safety protection, and in particular relates to a high-voltage electric test protection system. Background technique [0002] At present, electric energy has become an indispensable energy in the daily life and industrial production of human society, and electric energy is also an extremely important resource. Among them, the power system operating equipment has a protection system, which adopts a logic locking method to ensure the safety of equipment operation. A high level of safety is also required in the high-voltage electrical test work, but there is no in-depth study on the protection system in the test work. The high-voltage electrical test protection system sorts out and summarizes the problems existing in the high-voltage test work, and the targeted design of safety protection methods is an important point to improve the safety of the high-voltage electrical test work.
