Abstract
The utility model discloses an electric device, in particular a complete dry type composite casing high voltage bushing which is applicable for the power system ranging from 10KV to 220kV. When a high voltage conductor is threaded through wall or other equipments are earthed, the bushing serves as a high voltage device for electric insulation and mechanical support of the high voltage conductor. The high voltage bushing comprises a conductive rod 1, a main insulated layer 2 connected on the outside of the conductive rod 1, an insulating jacket 3 and a connection sleeve 4, wherein, the main insulated layer 2 is a multilayer parallel connection pure solid concentric column insulated layer consisting of at least two alternate solid layers. The insulating jacket 3 and the connection sleeve 4 are connected on the exterior of the main insulated layer 2. The bushing disclosed in the utility model contains no oil or gas, so that the bushing can prevent oil leakage, gas leakage and explosion. The utility model has the advantages of simple structure, small volume, light weight, firm structure in addition to easy delivery and installation, meeting the requirement of free from maintenance proposed by electricity authority.
Description
Technical field:
The utility model belongs to a kind of high-voltage electric device that uses when high-pressure conductor in the power equipment passes through wall or miscellaneous equipment (transformer etc.) grounding shell, particularly a kind of composite high-voltage casing.
Background technology:
At present in the electric power system when high-tension line passes through wall or equipment ground shell employed bushing all contain conducting rod, main insulating layer, insulating coating and branch sleeve etc., its version has following several basically: a kind of is traditional oil-filled condenser type and gas-insulating type, oil-filled capacitive structure is that main insulating layer is to be provided with at interval by insulating paper and aluminium foil strip (or semiconductor tape), must leave the gap between every layer, be filled with oil in the gap, also be filled with oil between main insulating layer and the insulating coating; The structure of gas-insulating type is to be air or other gas between conducting rod and the insulating coating; Another kind be very close to each other between main insulating layer and the insulating coating, combine closely, but main insulating layer is a multilayer dielectric layer, accompanies oil (silicone oil) between every layer; Also having a kind of then is that main insulating layer also is multilayer dielectric layer, very close to each other between every layer, but it is gapped and be filled with pasty masses (silicone grease) or gas between main insulating layer and the insulating coating, though existing bushing is difference to some extent structurally, but all contain non-solid oil or gas, therefore, exist gas leak of the oil leakage, electric property instability, machinery is poor with anti-pollution characteristic, maintenance workload is big, inflammable and explosively jeopardize different defectives such as the person and device security, useful life is short.
Summary of the invention:
The purpose of this utility model provides the composite high-voltage casing of a kind of not oil-containing or gas, to eliminate the various defectives that bushing was occurred of present use, improves power supply quality, reduces power supply cost.
Technical solution of the present utility model is: a kind of composite high-voltage casing, comprise conducting rod 1, the main insulating layer 2 that conducting rod 1 outside joins, insulating coating 3 and branch sleeve 4, described main insulating layer 2 is to be provided with at interval and the multilayer that forms of the combining closely pure solid concentric column insulating barrier of connecting by at least two kinds of solid layers, insulating coating 3 and branch sleeve 4 also with main insulating layer 2 outside close proximity.
Can with main insulating layer 2 measurement terminal 5 of joining, be connected to the running state monitoring device with measurement terminal 5.
Can be provided with current transformer 6 on the described branch sleeve 4.
Described solid layer is that dip-coating has the glass fiber material of epoxy resin and semicoductor capacitor all to press pole plate.
The material of described insulating coating 3 is a silicon rubber.
The utility model compared with prior art has following advantage:
1. product is totally-enclosed pure solid dry construction, does not contain any oil or gas, has avoided leakage of oil, gas leakage, inflammable and explosive hidden danger fully; Under the long-time running service condition, its electric and stable mechanical performance is reliable, and long service life has really reached the requirement of " non-maintaining " that power department proposes, and is producing and in servicely can not cause any pollution to environment;
2. simple in structure, volume is little, in light weight, should not damage, be convenient to transportation and install;
3. the main insulating layer structure reduces discharge inception voltage to greatest extent, and the voltage that has improved the pole plate end distributes, and mechanical structure strengthened (can reach the several times with the common rod iron of diameter), has improved the electric and mechanical performance of product;
4. insulating coating is the silicon rubber composite sheath, has improved the anti-dirty ability of product;
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment:
As shown in the figure: 1 is conducting rod, adopt copper rod (pipe) or aluminium bar (pipe) material to make, conducting rod 1 is formed capacitor core (solid concentric cylinder series capacitor) with main insulating layer 2, main insulating layer 2 is adding the special equipment that can adopt winding epoxy silk or filament cloth insulated tube (rod) man-hour, there are the glass fiber material of epoxy resin and semicoductor capacitor all to press pole plate to be provided with at interval dip-coating and disposable wound and solidified is molded on the contact tube 1, the main insulating layer that formation is combined closely, semicoductor capacitor all press every layer on pole plate along conducting rod 1 longitudinally length should successively successively decrease from internal layer to skin, the outermost layer of main insulating layer 2 is necessary for the glass fibre that dip-coating has epoxy resin, semicoductor capacitor all presses the number of plies of pole plate and every layer of dip-coating of being twined to have the thickness of the glass fiber material of epoxy resin to decide according to the requirement of products of different specifications, dip-coating has the glass fiber material of epoxy resin to play insulating effect, semicoductor capacitor all presses pole plate to play all pressure effects, and all pressures pole plate that also can adopt other dip-coating to have the insulating material of bonding agent maybe can play all pressure effects carries out coiling.The appearance close proximity of main insulating layer 2 has silicon rubber insulation overcoat 3 and branch sleeve 4, the silicon rubber insulation overcoat 3 at its two ends can adopt the surface of integral die one-step mould sulfidization molding at main insulating layer 2, form organic whole with capacitor core, not only improved production efficiency, the sealing property and the electric property of product have also been improved, its outdoor part adopts big umbellule umbrella shape, indoor part is isometrical umbrella, outdoor creepage grade distance is pressed the above fouling resistance rating design of III level, and indoor outer insulation property all satisfy the regulation of GB311.1 " insulation coordination of high-tension power transmission and transformation equipment ".The branch sleeve 4 that is installed in the capacitor core middle part adopts screw thread to hold out against structure and fixes, the two ends installing pressure equalizing cover 7 and the binding post 8 of capacitor core, the measurement terminal 5 of all pressing pole plate to be connected with the capacitor core outermost layer is installed on the branch sleeve 4, use during for the measurement electric property, also the monitor that is connected between measurement terminal and the ground can be installed, to monitor the running status of product, also can be according to user's needs, current transformer 6 is installed on branch sleeve 4, so that be in operation to electric power system provides the control metering signal, can improve reliability of products.
