The present invention discloses an anti-rustiness disconnecting switch. The anti-rustiness disconnecting switch comprises an incoming line contact rain cover, a channel steel rain cover and a switching-off blade; the upper side surface of the incoming line contact rain cover is provided with an incoming line contact seat; the lower side surface of the incoming line contact seat is provided with an incoming line contact terminal adjacent to the left side of the incoming line contact rain cover; the lower side surface of the incoming line contact seat is provided with a switching blade seat adjacent to the right side of the incoming line contact terminal; the middle of the switching blade seat is provided with a cushioning pad adjacent to the upper side surface of the incoming line contact seat; and the important connecting portion of the apparatus is provided with the protection cover, so that the influence of harsh environments which the disconnecting switch contacts with outdoors can be decreased, and therefore, the speed of rustiness can be decreased, and the failure of the operating mechanism of the disconnecting switch and poor contact performance of the electric conduction portion of the disconnecting switch which are caused by difficulty in rotating a disconnecting switch base which has been rusted for a long time can be avoided, the reliability of the disconnecting switch is greatly increased, and the personal safety of workers can be ensured.
Description
technical field [0001] The invention belongs to the technical field of comprehensive protection systems, and in particular relates to an anti-corrosion isolating switch. Background technique [0002] The isolating switch, that is, when it is in the off position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark. When it is in the close position, it can carry the current under normal circuit conditions and the current under abnormal conditions within a specified time. It is mainly to establish a reliable insulation gap during maintenance, and separate the equipment or lines that need to be repaired from the power supply with an obvious disconnection point to ensure the safety of maintenance personnel and equipment [0003] The isolating switch is an outdoor device. Affected by external conditions, it is difficult to rotate the base of the isolating switch after long-term corrosion, which leads to failu...
