Abstract
The utility model discloses an electric outgoing sleeve comprising an upper insulator and a lower insulator, wherein the upper insulator is sheathed with a large seal ring and then penetrates througha mounting hole on a metal partition board to be embedded into the lower insulator; a conducting rod is sheathed in a small seal ring and then penetrates through a through hole arranged at the middleof the upper insulator and the lower insulator; the end part of the conducting rod is fastened by a copper washer, a spring washer and a copper nut; one end of the upper insulator, matched with the lower insulator, is provided with a boss, and the other end thereof is provided with a dent part; and one end of the lower insulator, matched with the upper insulator, is provided with a groove matchedwith the boss, and the other end thereof is also provided with the dent part. The electric outgoing sleeve with the structure adopts the mutually embedded and matched boss and groove of the upper insulator and the lower insulator, thus increasing the creepage distance of the conducting rod and the metal partition board between the two insulators; and other ends of the upper insulator and the lowerinsulator are both provided with the dent part, thus increasing the creepage distance of the conducting rod and the metal partition board at an outer profile of the insulators, and decreasing the whole dimension.
Description
Technical field
The utility model relates to a kind of electric outlet sleeve pipe, especially relates to a kind of line position that goes out that is used to have High-Voltage Insulation, as the outlet sleeve pipe of transformer, electric capacity and power cabinet high-voltage output line and the High-Voltage Insulation of its housing need.
Background technology
In high voltage electric equipment, consider the electromagnetic shielding and the safety utilization of electric power of equipment, the housing of equipment often is the metal shell of ground connection, and the output of equipment high pressure is high voltage.Output the time need be passed the metal partion (metp) of housing in the high voltage slave unit, must guarantee this moment to have between high-tension output line and the metal partion (metp) enough withstand voltage, uses a kind of sleeve pipe always in high voltage electric equipment high voltage lead and metal partion (metp) are done the high-tension electricity isolation.As seen the main technical requirements of sleeve pipe is insulation property.
At present, the application of outlet sleeve pipe in high-tension apparatus is very general, and be of a great variety on performance and pattern, and traditional outlet sleeve pipe has: 1, adopt the insulation of upper and lower insulator to metal partion (metp); 2, adopt the insulation of plastic insulation guide rod and insulator to metal.The version of traditional outlet sleeve pipe, conducting rod and the metal partion (metp) creepage distance between two insulators is very little, the size that must strengthen outlet sleeve pipe if work under high voltage satisfies insulation, therefore, cause under the High-Voltage Insulation environment traditional huge, complex structure of lead collar pipe volume.Can't satisfy the requirement that need alleviate weight of equipment, reduction equipment volume and high insulating property.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of electric outlet sleeve pipe at problems of the prior art, its objective is to satisfy instructions for use little to the lead collar pipe volume under the High-Voltage Insulation environment, high insulating property.
The technical solution of the utility model is that this a kind of electric outlet sleeve pipe comprises insulator and following insulator, last insulator puts the installing hole that passes on the metal partion (metp) behind the large sealing packing ring and is embedded in down in the insulator, conducting rod passes insulator and the middle through hole of following insulator after putting small sealing ring, and the end of conducting rod is fastening by copper washer, bullet packing ring and copper nut.
A described end of going up the insulator cooperation of insulator up and down is provided with boss, and the other end of last insulator is provided with recess, and an end that matches with last insulator on the following insulator is provided with the groove that matches with boss, and the other end of following insulator also is provided with recess.
The copper washer of described conducting rod one end has two at least.
The copper washer of described conducting rod one end has two, and lead-out wire is connected between two copper washers of same end.
A kind of electric lead collar pipe with above-mentioned special construction has the following advantages:
1, the electric outlet sleeve pipe employing of this kind is gone up insulator and is embedded boss and the groove that cooperates mutually with following insulator, increased conducting rod and the metal partion (metp) creepage distance between two insulators, the other end at last insulator and following insulator is equipped with a recess, conducting rod and metal partion (metp) have been increased at the creepage distance of insulator outline and reduced overall dimensions, make under the same size condition, the withstand voltage properties of this outlet sleeve pipe is traditional outlet sleeve pipe 2-3 times, has improved the reliability of equipment.
2, the end of the conducting rod of this electric outlet sleeve pipe makes large sealing packing ring and small sealing ring stressed compressing simultaneously with copper washer, bullet packing ring and copper nut and tight, makes this outlet sleeve pipe and metal partion (metp) have linking together of electric insulation and sealing.
3, this electric lead collar tubular construction is simple, is convenient to processing, has reduced manufacturing cost.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
