Abstract
The utility model relates to a power transmission line supporting tool and particularly relates to a 10kV quick-assembly insulating type paying off and supporting frame which is particularly matched with power transformers, thawing devices and thawing circuits in 66kV power transmission line moving type alternating current thawing devices. The frame comprises an insulating paying off cross arm which is supported by two fixing bases, a plurality of insulators and paying off pulleys are arranged on the cross arm, lead grooves are arranged on insulators, and connecting supporting pipes are connected in an vertical insertion mode between the cross arm and fixing bases respectively. The supporting frame adopts an assembly and insertion structure and is simple in structure, small in volume, light in weight and convenient to install, transport and store. Fixing bases adopt a crane leg structure design and have the adequate dead weight and supporting legs with sufficient lengths, so that the supporting frame is stable on the condition that acting forces of various directions are exerted by leads on the frame. Paying off is implemented easily due to paying off pulleys.
Description
Technical field
The utility model relates to a kind of power transmission line supporting tool, and promptly 10kV assembles insulated type unwrapping wire and bracing frame fast, is specially adapted to the supporting use in power transformer, deicing device and the DC ice-melting in the portable interchange of the 66kV transmission line deicing device.
Background technology
In the prior art, behind the powerline ice-covering, possibly cause device damage such as conductor cord disconnection, shaft tower topple; In icing comes off process; Possibly cause that circuit waves repeatedly short circuit tripping operation, the operation of serious threat substation safety, influence is to the reliable electricity consumption of user's security.The Northeast's daily temperature changes greatly, and because of there's a sudden fall in temperature, the icing time is long behind the wire icing, removes very difficulty.Present portable deicing device adopts the DC ice melting scheme more, needs high current power electronic rectifier equipment, complex equipments, and cost is high; Exchange deicing device and adopt stationary structure more, equipment disposition point is many, and cost is high.In conjunction with on-the-spot actual, the 66kV transformer station of operation does not have the ice-melt facility at present, receives on-the-spot restriction to build relatively difficulty of special-purpose ice-melt facility, needs to propose concrete settling mode.The portable deicing device that exchanges of 66kV transmission line arises at the historic moment.Under low temperature environment, adopt conventional cable or insulated wire, when existing exhibition to put to the problem of insulation harm; Ice melting current is big, and the required cross-section of cable is big, weight is big, rigidity is big, and on-the-spot artificial exhibition is put with the wiring difficulty very big.For realizing that the transmission line movable type exchanges deicing device and realizes connecting fast quick group of upright line tower structure that need be special-purpose with the lead that is connected between system.
The utility model content
The purpose of the utility model is to above-mentioned deficiency a kind of quick assembling insulated type unwrapping wire and bracing frame simple in structure, easy to assembly to be provided.
The technical solution of the utility model is: assemble the insulation unwrapping wire cross-arm that insulated type unwrapping wire and bracing frame comprise that two firm bankings support fast, be placed with a plurality of insulators, pulley block on the cross-arm, metallic channel is arranged on the insulator; Connect stay pipe respectively and vertical grafting between cross-arm and the firm banking.
Firm banking is a disc structure, and the disk upper edge even level of circumference is plugged with a plurality of supporting legs (radially).Have gland on the metallic channel.
This support mainly is applicable to support, the charging operation of setting up of electric power system 10kV lead and lead.
The utility model has the advantages that: 1, this support adopts combination, connected structure, and simple in structure, easy for installation, volume is little, and is in light weight, is convenient to very much installation and transportation, preserves.2, firm banking adopts lifting stand leg formula structural design, and enough deadweights and sufficiently long supporting leg (can according to circumstances prolong) are arranged, and has guaranteed that support is enough stable under the situation that receives lead all directions active force.3, pulley block makes unwrapping wire lighter.4, metallic channel has gland, can effectively prevent to run line, and lead is moved in groove.
To combine accompanying drawing that the execution mode of the utility model is described in further detail below.
Description of drawings
Fig. 1 is the utility model structure diagram.
Embodiment
Referring to Fig. 1, component names is following: cross-arm 29, metallic channel 31 and gland 32, lead 33; Insulator 34, pulley block 35, pulley fixed frame 36 and gland 37; Insulator bolt 38 and hold-down nut 39, female pipe 40, firm banking supporting leg 41 are supported in firm banking 27, connection stay pipe 28 and connection.
Assembling insulated type unwrapping wire and bracing frame comprise the insulation unwrapping wire cross-arm 29 that two firm bankings 27 support fast, are placed with three 10kV insulators 34 and three pulley blocks 35 on the cross-arm 29, make things convenient for flexible conductor to open up fast and put, and prevent wearing and tearing.Metallic channel 31 and gland 32 are arranged on the insulator 34; Connect stay pipe 28 respectively and vertical grafting between cross-arm 29 and the firm banking 27.Firm banking 27 is a disc structure, and enough deadweights are arranged, and the disk upper edge even level of circumference is plugged with four supporting legs 41 (radially).
Firm banking 27 adopts lifting stand leg formula structural design, increases physical dimension between support and ground, improves the resistance to overturning of support, reduces weight support frame.
Claims (2)
1. assemble insulated type unwrapping wire and bracing frame fast for one kind; It is characterized in that comprising the insulation unwrapping wire cross-arm (29) of two firm bankings (27) support; Be placed with a plurality of insulators (34), pulley block (35) on the cross-arm (29), metallic channel (31) is arranged on the insulator (34); Connect stay pipe (28) respectively and vertical grafting between cross-arm (29) and the firm banking (27).
