Abstract

Collect electric line ground wire erection method the invention discloses one kind, include early stage annex and install and two steps of later stage spreading lead wire and earth wire, it is ensured that the smooth erection of ground wire, the Stability Analysis of Structures after erection, it is ensured that the smooth of later stage current collection line cord is laid.

Description

One kind collection electric line ground wire erection method

Technical field

The present invention relates to ground wire construction field, specifically one kind kind current collection circuit ground wire erection method

Background technology

Arrived it is well known that the Chinese government makes promise in Copenhagen climate change conference in 2009 to international community The year two thousand twenty unit GDP CO2 emissions declined 40%~50% than 2005, and non-fossil energy will meet this country 15% energy demand, this development scale and progress to the following wind-powered electricity generation of China etc. is proposed unprecedented expectation, accelerates wind energy money The utilization in source with exploitation by as the important measure that the strategy of sustainable development is realized in China's considerably long one period, to the year two thousand twenty China's wind-powered electricity generation installation reaches 2.3 hundred million KW；Big good development environment and opportunity are provided for our Wind Power Developments.

During the foundation construction of wind power plant is built, current collection line cord lays the normal operation for determining blower fan and wind power plant The normal of middle every circuit element is used, and the erection of conductor wire determines the stabilization laid of later stage current collection line cord Property.

The content of the invention

Collect electric line ground wire erection method the technical problem to be solved in the present invention is to provide one kind, include early stage annex Install and two steps of later stage spreading lead wire and earth wire, it is ensured that the smooth erection of ground wire, the Stability Analysis of Structures after erection, it is ensured that after The smooth of phase current collection line cord is laid.

The technical scheme is that：

One kind collection electric line ground wire erection method, includes following steps：

（1）, ground wire annex install：After the observation of stringing sag is finished, carry out sag adjustment by shelves by strain section and sub-conductor is adjusted It is flat, meet after the requirement of this strain section sag, each tower position is printed in this strain section, is printed positioned at hanging wire point vertical line and wire Intersection point on, then suspension clamp is installed at printing；Suspension clamp carries out wire jumper installation after installing, when wire jumper is installed, make Wire jumper is in stretched wire state, and suspension string is vertical；

（2）, spreading lead wire and earth wire：After ground wire wiring, ground wire unnecessary in each shelves is evacuated at traction stringing anchor support, until Untill ground wire departs from ground, then wire is connected with turnbuckle, with being twisted haulage cable come stringing lead；Treat that sag will When will be close to setting setting, slowly stringing lead, in order to sag observation；Sag observation make sag value stabilization in setting i.e. Print, by ground wire, slowly pine anchors to ground, and at a certain distance from before printing a little, prints certainly and a little measures the line length of cutting, Equal to the actual size of porcelain vase hardware string, then strain clamp, stockbridge damper and insulator chain, last hanging wire, to list are installed Insulator string is to connect a turnbuckle in mill end head to be clipped on wire, and then insulator chain is tied up on mill rope with coir rope, driven Dynamic be twisted hangs over insulator pull-up on cross-arm hanging wire point, is, in the mill U-shaped ring of end head lifting, to be connected in double insulator string Afterwards on duplex plate, then driving, which is twisted, hangs over double insulator string pull-up at cross-arm hanging wire point.

When described ground wire wiring is using mechanical unwrapping wire, drum placement location should be selected in unwrapping wire apart from one end, so as to Another side-lining exhibition, during manual stringing, drum answers cloth to be placed on the centre of unwrapping wire distance, to be unfolded to two.

During described sag observation, when using an observation shelves, in order that front and rear each shelves sag meets setting, it should make Observe sag more smaller than standard value, then return loose ground wire, make observation sag more bigger than standard value, so return after answering twice, Tightening up again makes sag value stabilization to be printed in setting；When observing sag using multi gear, make first apart from stringing shaft tower most The sag of a remote observation shelves reaches setting, then loosens wire, then each observation shelves is all reached rule from far near successively Definite value, you can print.

Advantages of the present invention：

Ground wire erecting structure of the present invention is stable, meets electric and technological requirement, and construction procedure is reasonable in design clear, it is ensured that after The smooth of phase current collection line cord is laid.

Embodiment

The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation Example only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common The every other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model that the present invention is protected Enclose.

（2）, spreading lead wire and earth wire：When ground wire wiring is using mechanical unwrapping wire, drum placement location should be selected in unwrapping wire apart from one end, with Just to another side-lining exhibition, during manual stringing, drum answers cloth to be placed on the centre of unwrapping wire distance, to be unfolded to two；Ground wire After wiring, ground wire unnecessary in each shelves is evacuated at traction stringing anchor support, untill ground wire departs from ground, then will Wire is connected with turnbuckle, with being twisted haulage cable come stringing lead；When sag will be close to setting setting, slowly receive Tight wire, in order to sag observation；During sag observation, when using an observation shelves, in order that front and rear each shelves sag meets rule Definite value, should make observation sag more smaller than standard value, then return loose ground wire, make observation sag more bigger than standard value, so return After answering twice, then tightening up makes sag value stabilization to be printed in setting；When observing sag using multi gear, make distance tight first The sag of a farthest observation shelves of line bar tower reaches setting, then loosens wire, then make each observation shelves from far near successively All reach setting, you can print；By ground wire, slowly pine anchors to ground, and at a certain distance from before printing a little, prints certainly Point measures the line length of cutting, equal to the actual size of porcelain vase hardware string, then installs strain clamp, stockbridge damper and insulator chain, Last hanging wire, is to connect a turnbuckle in mill end head to be clipped on wire to single insulator string, then insulator chain is used Coir rope is tied up on mill rope, and driving, which is twisted, hangs over insulator pull-up on cross-arm hanging wire point, is in mill end head to double insulator string With the U-shaped ring of lifting, it is connected on rear duplex plate, then driving, which is twisted, hangs over double insulator string pull-up at cross-arm hanging wire point.

Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
