A test device for fish resistance to power frequency electric shock using a rotating electrode plate

Abstract

The invention discloses a fish body power frequency-tolerant electric shock testing device adopting a rotating type electrode plate. The testing device comprises a test box body, a test medium, a testee, a sliding rail mechanism, a current adjusting system and a test electrode mechanism; the test box body is provided with a test chamber; the test medium is contained in the test chamber; the testee is placed in the test medium; the sliding rail mechanism is arranged on the test box body and located in the test chamber; the current adjusting system is used for providing power frequency follow currents; the test electrode mechanism is slidably arranged on the sliding rail mechanism and electrically connected with the current adjusting system. By enabling the test electrode mechanism to slide on the sliding rail mechanism and adjusting the size of the follow currents, the condition that a fish body is influenced by the follow currents which come from different angles and directions or have different sizes in a fish pond can be simulated, workers can carry out corresponding protection measures, and the fish safety is guaranteed. Meanwhile, the testing device is simple in structure, convenient to operate and high in safety and reliability.

Description

technical field [0001] The invention relates to the technical field of electric power test, in particular to a test device for fish body resistance to power frequency electric shock using a rotating electrode plate. Background technique [0002] Around my country's "West-to-East Electricity Transmission" strategic project, in order to meet the continuous growth of power demand in the future, the State Grid Corporation of China has proposed to accelerate the construction of UHV power grids consisting of million-volt AC and plus or minus 800-kilovolt DC systems. The development goals have also further accelerated the construction of high-voltage, long-distance, and large-capacity transmission line projects. The tower is an indispensable link in the transmission line, and the grounding grid of the tower is of great significance to escort the safe operation of the transmission system. In actual work, the tower grounding grid plays a role in quickly discharging fault current and ...

Problems solved by technology

Although the grounding network of the tower can ensure the safety of the nearby personal safety, and the reliable action of the relay protection device cuts off the fault current in time, when the power frequency continuous flow formed within 40 milliseconds before the relay protection action flows through the substation or the fish pond near the tower , the current flowing into the fish pond is bound to have an electric shock effect on the fish in the fish pond, and may even cause the death of the fish in serious cases, which will not only cause great economic losses, but also cause a gap between the local power supply bureau and the local farmers. more disputes

Therefore, it is extremely necessary to carry out corresponding protection work through experiments to know that fish animals are subjected to currents of different angles, sizes and times in fish ponds. Continuous flow experimental device
