Abstract
The utility model relates to a high-voltage wall feed-through sleeve with a suppressor resistor. The high-voltage wall feed-through sleeve having the benefits of simple structure and reliability in use comprises an input high tension line, a wall feed-through sleeve, epoxy resin, a resistor and an output connector, wherein the high tension line is connected in series with the resistor and the output connector; then the high tension line, the resistor, and the output connector are placed in the wall feed-through sleeve; and an insulating material is adopted for pour-sealing, so as to form an integral wall feed-through sleeve with the suppressor resistor. Since the suppressor resistor is placed in the wall feed-through sleeve and is sealed by the insulating material, a specific insulation space for the suppressor resistor is not needed, thereby saving volume of an electricity box of equipment, and achieving high insulation coefficient, reliability and stability in work, and more safety in use.
Description
Technical field
The utility model relates to high voltage electrical apparatus technical field, is specifically related to a kind of high-voltage wall bushing.
Technical background
At present in large-scale electrostatic dust collection equipment, in order effectively to absorb the high order harmonic component composition of high-voltage rectifying transformer secondary circuit, prevent output loop generation resonance, effectively the protection rectifier transformer is sent high-voltage DC power supply into the cleaning equipment electric field through wall bushing again after the rectifier transformer high-voltage output end is installed damping resistance; And field erected damping resistance, what have is installed between rectifier transformer output and the high voltage isolator, between the high pressure that is installed in high voltage isolator and electric field that also has is introduced; The general employing of the damping resistance of existing electric precipitation is exposed to airborne mounting means, and in some small-sized electrostatic purifiers, on oil smoke, purifying and recovering system equipment, if owing to also adopt the mounting means of large-scale electric precipitation, need around damping resistance, keep enough insulating spaces, tend to make the long-pending body of equipment electrical control case to become big, and the scene of using exists a large amount of oil smoke, mist of oil, cause damping resistance to be stained with a large amount of greasy dirts easily and break down, and potential safety hazard may occur.
Summary of the invention
The utility model provides a kind of high-voltage wall bushing of simple in structure, service-strong band damping resistance.
Technical solution provided by the utility model is: a kind of high-voltage wall bushing, comprise high-voltage insulating wire, wall bushing, insulating material, damping resistance and high-voltage output connector, high-voltage insulating wire and damping resistance, high-voltage output connector are connected in series, high-voltage insulating wire is connected with external power source, high-voltage output connector runs through wall bushing and is connected with high voltage electric field, damping resistance is installed in the sleeve of wall bushing, is filled with insulating material in the sleeve with the damping resistance sealed insulation.
Described damping resistance is in series by 3-8 resistance, and series connection back total resistance value is in 600 Ω-4000 Ω scope.
Described insulating material is an epoxy resin.
Described high-voltage output connector is a screw.
Compared with prior art, the utlity model has following advantage:
1, since damping resistance put into wall bushing and sealed with insulating material, the insulating coefficient height, working stability is reliable.
2, need not reserve insulating space for damping resistance, save the volume of the electronic box of equipment.
3, the electrification in high voltage component package is used safer in insulating space.
Description of drawings
Fig. 1 is the cutaway view of the utility model high-voltage wall bushing.
Embodiment:
As shown in Figure 1, the utility model high-voltage wall bushing is made up of high-voltage insulating wire 1, wall bushing 2, insulating material 3, damping resistance 4, high-voltage output connector 5.The damping resistance of present embodiment is in series by four resistance, put into its inside from an end of wall bushing 2 after high-voltage insulating wire 1 and damping resistance 4, high-voltage output connector 5 coupled in series, the part of high-voltage output connector 5 runs through the other end of wall bushing 2 as be connected usefulness with high voltage electric field, with insulating material 3 whole damping resistances 4, part high-voltage insulating wire 1 in wall bushing and an end embedding of high-voltage output connector 5 are fixed in the wall bushing 2 again, thereby have reached the purpose of insulated enclosure.
As the preferred insulating material of the utility model high-voltage wall bushing is epoxy resin, and described high-voltage output connector 5 can be screw.
