Abstract
The utility model discloses an insulating porcelain plate for a locomotive resistor cabinet, comprising a porcelain plate body, wherein the upper surface of the porcelain plate body is provided with an non-through positioning screw hole, and the side surface of the porcelain plate body is provided with a groove. The insulating porcelain plate for a locomotive resistor cabinet has the characteristics of being reasonable in structure design, long in creepage distance and good in insulating effect, etc.
Description
Technical field
The utility model relates to a kind of insulation porcelain plate, and is especially relevant with locomotive resistor box insulation porcelain plate.
Background technology
Existing locomotive resistor box insulation porcelain plate adopts the vertical bar slab construction usually, adopts the through hole bolt to be connected between electric conductor and the insulation porcelain plate up and down, exists deficiencies such as creepage distance is lacked, insulation effect is poor, structural design is unreasonable.
Summary of the invention
The purpose of the utility model provides a kind of reasonable in design, creepage distance is long, insulation effect is good locomotive resistor box insulation porcelain plate.
For achieving the above object, the utility model is realized through following technical scheme.Locomotive resistor box insulation porcelain plate comprises the porcelain plate body, is provided with the positioning screw hole of non through hole at the upper surface of porcelain plate body, on the side of porcelain plate body, has groove.
Described locomotive resistor box insulation porcelain plate all has the groove that is connected on four sides of porcelain plate body.
Described locomotive resistor box insulation porcelain plate is provided with the connection screw of the non through hole of band boss on the lower surface of porcelain plate body, positioning screw hole is with to be connected screw not connected.
The utility model has been owing to adopted technique scheme, thereby has following beneficial effect.(1) be owing to have groove in the side of porcelain plate body, increased creepage distance, improved the design of insulation porcelain plate, the insulation porcelain plate is taken up room dwindle, save material, insulation effect improves greatly; (2) be owing to be provided with the positioning screw hole and the screw that is connected of being with boss of not connected non through hole at the upper and lower surfaces of porcelain plate body, better connection insulation effect is not only arranged, and more reliable with being connected of electric conductor up and down.
