Embodiment Construction

[0019] The present invention is further described with accompanying drawing as embodiment:

[0020] refer to figure 1 : The present invention is made up of ship bottom type top surface insulator sheet 1, top fittings 2, small shed shed insulator sheet 3, rhombus support column 4, bottom frame fastening seat 5, shed inner frost protection pad 6 etc. The chassis fastening seat 5 is installed on the roof of the electric locomotive, and the top fittings 2 support equipment such as heavier locomotive pantographs. The left and right sides are the acute angles of the diamond-shaped support column insulators on the top surface of the bottom of the ship, which are suitable for the operation of the locomotive in the front and rear directions.

[0021] refer to figure 2 : the front of the present invention's ship bottom type top surface rhombic support column insulator string, it faces the forward or backward direction of locomotive operation, and the positive side area is smaller tha...

Abstract

The invention relates to a boat-bottom-type top face rhombus supporting pillar insulator string of the roof of an electric locomotive. The boat-bottom-type top face rhombus supporting pillar insulator string is composed of a boat-bottom-type top face insulator sheet (1), a top armor clamp (2), a small umbrella skirt insulator sheet (3), a rhombus supporting pillar (4), an underframe fastening base (5) and an umbrella skirt inner side frost stopping pad (6). The boat-bottom-type top face rhombus supporting pillar insulator string is installed on the roof of the electric locomotive, the left side and the right side are provided with the boat-bottom-type top face insulator sheet (1) and the acute corner of the rhombus supporting pillar (4) respectively, when the electric locomotive runs in the heavy fog weather, the rhombus acute corner of the rhombus supporting pillar (4) guides collided supercooled water drop fog, ice crystal fog and the like in the running direction to the two sides of the rhombus supporting pillar (4), the ice crystal fog is prevented from being gathered on the rhombus supporting pillar (4) to form frost-shaped ice, and fog flicking faults caused by formation of conductive layers on the surface of the insulator string are prevented. The umbrella skirt inner side frost stopping pad (6) rich in grease has the hydrophobic character, dirty fog water drops can be prevented from being coagulated on the surface of the umbrella skirt inner side frost stopping pad (6), the inner sides of umbrella skirts of the supporting pillar insulator string are kept in the drying state, and the fog flicking faults caused by the formation of the conductive layers on the surface of the insulator string are prevented.

Description

1. Technical field [0001] The invention relates to a support insulator string used on the roof of an electric locomotive, in particular to a support insulator string composed of a bottom-shaped top insulator piece, a top fitting, a small shed insulator piece, a diamond-shaped support column, a bottom frame fastening seat, and the inner side of the shed. The insulator string of rhombus-shaped support column on the bottom of the ship composed of anti-frost pads and so on. 2. Technical background [0002] Although there are various types of electric locomotives in various countries in the world, the main power supply circuit on the top of the electric locomotive uses metal conductive rods and supporting insulators for high-voltage power transmission. Both use the pantograph slide to collect high-voltage electricity, transmit it to the metal conductive rod by the pantograph frame, and then feed it to the power load of the electric locomotive. The pantograph and conductive rods ...
