A salt spray corrosion test device for electric compound grease

Abstract

The invention discloses a salt spray corrosion test device for electric compound grease. The device comprises a box body, a joint simulation mechanism for carrying out a penetration corrosion test onthe compound grease by salt spray passing through the gap is arranged in the box body. A multi-stage gap adjuster is gradually pulled by the timing puller, the gap size and depth of the gap simulationblock are changed, therefore, the evolution of the compound grease along with time under a high-temperature condition is simulated, the internal gap is gradually increased along with the increase ofthe corrosion degree of the salt spray, the salt spray permeation conditions and the corrosion efficiency of different permeation degrees on the compound grease under gaps with different sizes and depths can be known in real time in the simulation process, and an operator can obtain the best protection; and in addition, the salt spray ring sprayer can be used for simulating the situation that tinysalt spray is attached to the outer sleeve of the cable joint under the natural environment, so that the salt spray gradually permeates into the conductive paste, and therefore, shell protection measures at the cable joint are provided for a user.

Description

technical field [0001] The invention relates to the field of electric composite grease, in particular to a salt spray corrosion test device for electric composite grease. Background technique [0002] Electric compound grease, also known as conductive paste, is a neutral conductive dressing with good electrical contact performance. It is suitable for the contact surface of high and low voltage electrical appliance busbar overlaps and various electrical joints, which can significantly reduce the contact resistance, thereby obtaining good economic benefits for energy saving. [0003] It needs to be protected according to the external environment when it is used. One of the protective measures in the artificial environment three-defense series is salt spray corrosion protection, and a simulation test is required before protection to ensure that the product's protective measures are optimal, so that the salt spray test chamber can be used, which is The reliability of the corro...
