Description
Technical Field
The invention belongs to the technical field of high-voltage power, and particularly relates to a high-voltage bushing salt corrosion prevention device and method based on charged perfusion.
Background
Because 10Kv transmission lines involve more points and longer lines, and the number of devices is large, the protection measures are few, the basic conditions of operation and maintenance are poor, and the adverse factors such as interference of the open-air environment and weather are also born, the possibility of line faults is high, and the most prominent is salt corrosion.
Salt corrosion has become a natural disaster, and long-term salt corrosion causes damage to a high-voltage bushing of a power transmission line, leads to non-insulation of a lead wire to the ground and cannot play a role of fixing the lead wire, and the transformer bushing is one of current-carrying elements of a transformer. Consequences of the rupture of the transformer high-voltage bushing: 1. after the high-voltage bushing of the transformer is broken, a cable joint is burnt out, electric leakage is easy to occur, and automatic tripping is easy to cause power failure particularly in humid air and rainy days. 2. The transformer lead is led out through the inner cavity of the transformer bushing and connected with an external circuit, the lead is supported and insulated by the bushing, water enters due to the fact that a cap cover (for a military cap) at the upper end of the bushing is not tightly sealed, and the main insulation of the lead is affected with damp and breaks down. 3. If the surface of the sleeve of the power transformer is affected with damp, the area network voltage is reduced; if dirt such as dust, oil stain, salt, soot and the like exists on the sleeve, the switch is often tripped as a result. During the operation of the power transformer, if salt frost and dirt are found, cleaning and corrosion prevention are carried out in time so as to ensure normal power supply of the transformer substation.
In the traditional method, equipment power failure or live-line operation is required for inspecting or replacing the high-voltage sleeve, so that economic loss is caused if the equipment is powered off, and the power supply reliability is reduced; the live working processing method needs personnel to climb a tower for operation, indirectly or directly contacts a charged body, and has higher operation risk.
