Embodiment Construction

[0019] With reference to accompanying drawing, further illustrate the present invention:

[0020] Such as figure 1 , figure 2 As shown, a knife switch online salt spray test device includes a salt spray test chamber A providing a salt spray atmosphere, a knife switch installation part B installed in the salt spray test chamber A, and a motion control part C.

[0021] The salt spray test box A includes a box body 11 and a box cover 5 . The casing 11 and the casing cover 5 are combined by water sealing. A box wall of the box body 11 is provided with a square opening, and the sealing end cover 4 is connected with a screw and a sealing ring to cover the square hole to realize sealing, thus avoiding the leakage of gas inside the salt spray test box. There is a round hole on the sealing end cover 4 to pass through the transmission shaft 6, and the shaft sealing end cover 3 is used to prevent the internal gas from leaking through the shaft gap. The shaft sealing end cover 3 is co...

Abstract

A disconnecting link online salt spray test apparatus comprises a salt spray test box for provided a salt spray atmosphere, a disconnecting link installation plate for installing a disconnecting link, a disconnecting link operation arm for opening / closing a disconnecting link, and a movement controlling mechanism. The movement controlling mechanism comprises a rotary motion part for outputting rotary reciprocating motions. One end of the disconnecting link operation arm is fixedly connected to the rotary reciprocating end of the rotary motion part, and the other end is interlinked to a disconnecting link operating handle. The test apparatus has the advantages that a disconnecting link can open and close for predetermined times in a predetermined period in a salt spray atmosphere and the corrosion resistant performance of the disconnecting link can be truly represented.

Description

technical field [0001] The invention relates to an online salt spray test device for dynamic testing of knife gates. [0002] technical background [0003] Knife switch is a kind of manual switch of electric equipment, alias switch knife, generally used for low-voltage power, there are single-phase switch and three-phase switch. Generally, it is composed of a porcelain base, a plastic cover, and copper parts. The upper part is the wire inlet, the lower part is the wire outlet, and the fuse is installed in the middle. [0004] The copper part of the knife switch is the core component, and the contact of the copper part is controlled by the movement of the knife switch handle to realize the on-off of the circuit. Contact failure is the main failure mode. The base copper of the contact will be oxidized and corroded by the gas in the atmosphere, thus affecting the contact performance. For knife gates that are applied at the seaside, they must be able to be used in severe salt ...
