Background technology
Composite outer insulation spark gap internal wetted mostly is control process and the most sternly causes that integral sealing is bad to be caused, and embeds
It is one of the main reasons that formula flange bolt hole position ruptures.Wherein above flange, binding post is that embedded bolt is fixed, and epoxy is exhausted
Being irrigated by glass cement between edge cylinder and valve block, to reach the purpose of protection against the tide, but often the carelessness of production technology easily causes sealing not
Good problem.
Summary of the invention
In place of above-mentioned the deficiencies in the prior art, the present invention provides a kind of 66kV composite outer insulation spark gap to use
Direct-connected flange.Its purpose is to solve fault of construction and the problem of poor sealing performance of the multiple spark gap of fault.
In order to realize foregoing invention purpose, the present invention is achieved through the following technical solutions:
A kind of 66kV direct-connected flange of composite outer insulation spark gap, is connected on upper flange by patch panel, lightning arrester body
Inside includes electrode, spring, resistor disc, filling glue and bottom electrode, is fixed by epoxy tube；Resistor disc is stacked in epoxy tube
In, use spring compression；Lightning arrester body is electrically connected with patch panel by upper electrode and bottom electrode, between epoxy tube and resistor disc
Glue is filled in perfusion；It is provided with silicon rubber umbrella skirt in the outside of epoxy tube；Base is positioned at bottom lightning arrester body.
Filling glue is all irrigated at spring between described upper flange and resistor disc and upper electrode.
Described patch panel is welded to connect with upper flange.
Described patch panel is connected with upper flange extraction, and its connected mode is direct-connected.
Described upper flange is cylindrical structural.
Described upper flange is separated with top patch panel, and top patch panel is connected wire and is fixed on bolt fastening with electrical network
Kong Zhong.
Present invention technology relatively now has the advantage that and beneficial effect:
The present invention can thoroughly stop the poor sealing that conventional embedded flange spiro keyhole position crackle causes, and improves the whole of spark gap
Body sealing property, effective raising work efficiency and work quality.The present invention is applied to 66kV system, by patch panel and upper flange
Separate, make the transition of operation of connecting lead wire to outside lightning arrester body, in effectively prevention causes spark gap owing to spiro keyhole position ruptures
Portion makes moist.Owing to the present invention changes the mode of conventional patch panel and the upper flange embedded wiring of employing, substantially reduce lightning-arrest
Device is because of design technology and the bad phenomenon causing making moist of mounting process.
Below in conjunction with the accompanying drawings and specific embodiment, technical scheme is described in detail.

Detailed description of the invention
The present invention is a kind of 66kV direct-connected flange of composite outer insulation spark gap, as it is shown in figure 1, Fig. 1 is the present invention
66kV composite outer insulation direct-connected flange population structure schematic diagram.The present invention is to be fixed on upper flange 2 by patch panel 1, connects
Line plate 1 is connected with upper flange 2 extraction, and spark gap external insulation is silicon rubber umbrella skirt 7, inside lightning arrester body by upper electrode 3,
Spring 4, resistor disc 6, filling glue 8, bottom electrode 9 form, epoxy tube 5 fix.Patch panel 1 by welding by the way of and upper flange
2 are joined directly together, and resistor disc 6 carries out being stacked in epoxy tube 5 according to the sheet number of design of dispatching from the factory, and compresses with spring 4, lightning arrester body
It is electrically connected with patch panel 1 by upper electrode 3 and bottom electrode 6, uses filling glue 8 to be sealed in epoxy tube 5 by lightning arrester body；
Be provided with silicon rubber umbrella skirt 7 in the outside of epoxy tube 5, external insulation uses composite outer insulation i.e. silicon rubber umbrella skirt 7 to strengthen spark gap
Antifouling work ability；Base 10 is positioned at lightning arrester body bottommost, rises and installs positioning action.
As in figure 2 it is shown, Fig. 2 is direct-connected flange arrangement schematic diagram in Fig. 1.Cylindrical upper flange 2 and top patch panel 1
Connected mode embedded is changed into direct-connected by original, is separated with patch panel 1 by upper flange 2, for be connected with electrical network
Wire is directly fixed in bolt fastening hole 11 by bolt.Tests prove that, favorable sealing property of the present invention.
The present invention uses direct-connected upper flange to be connected with lead-in wire, has thoroughly stopped conventional embedded flange spiro keyhole position crackle
The poor sealing caused.Glue 8 is filled by perfusion, such as waterproof glass glue, to reach sealed damp-proof between epoxy tube 5 and resistor disc 6
Effect.And spring 4 between upper flange 2 and resistor disc 6 and upper electrode 3 position all irrigate filling glue 8, such as waterproof glass glue,
