Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0020] The invention proposes a simple device for protecting the roof insulators aiming at the fog flashover and pollution flashover phenomena of locomotive roof insulators which generally occur. The specific implementation will be described below in conjunction with the accompanying drawings.

[0021] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the structure of a fog flash and pollution flashover protection device for locomotive roof insulators is as follows: the protective cover 4 surrounds the locomotive roof insulator 2, and the front part of the protective cover 4 has a windshield 7, a cover plate 5 and a soot blowing channel 6. The rear part of the protective cover 4 has an upper baffle 8; the cover plate 5 is installed at the leftmost end of the protective cover 4, one end of the soot blowing channel 6 is connected to the cover plate 5, ...

Abstract

The invention discloses a fog flashover and pollution flashover protective device for an insulator at the top of a locomotive and belongs to the technical field of electric utility protection and traffic safety. The fog flashover and pollution flashover protective device is structurally characterized in that a protection hood encircles the insulator at the top of the locomotive; the front part of the protection hood is provided with an upwind baffle, a cover plate and a soot blowing channel, and the rear part of the protection hood is provided with an upper baffle; the cover plate is arranged at the leftmost end of the protection hood; one end of the soot blowing channel is connected with the cover plate, and the other end of the soot blowing channel is connected with the internal surface of the protection hood; and the upwind baffle and the upper baffle are provided with oblique surfaces which are of a tooth-shaped groove structure. The fog flashover and pollution flashover protective device has the beneficial effects that the structure is simple, and the fog flashover and pollution flashover protective device is convenient to implement and easy to replace; the bottom of the protection hood is provided with a bolt, so that the fog flashover and pollution flashover protective device is only needed to be connected with the top of the locomotive, and the arrangement of the existing top structure of the locomotive and electric appliance components is not influenced; and the probability that the insulator is subjected to flashover breakthrough is reduced, and the traveling safety of the locomotive is ensured.

Description

technical field [0001] The invention belongs to the technical field of electrical facility protection and transportation safety. In particular, it relates to a fog flash and pollution flash protection device for locomotive roof insulators. Background technique [0002] At present, the top power supply main circuits of various electric locomotives use metal guide rods and support insulators for high-voltage power transmission. The roof pantograph and conductive rods are all bare and non-insulated metal rods, and the insulation of tens of thousands of volts of high voltage electricity to ground depends on the support of insulators. Roof insulators are the key to ensuring normal driving and driving safety, and roof insulators are also one of the main components that cause fog flashover and pollution flashover accidents. [0003] Fog flash is a high-voltage breakdown discharge phenomenon on the roof that may occur on different types of electric locomotives in special seasons a...
