Description
Technical field
The present invention relates to power industry transformer station field, is specifically that a kind of transforming plant assembly type that is used for builds lightning protection system
The new breaking of contact tank mounting structure of system.
Background technology
With the development of Chinese society economy and power grid construction, assembled architecture is showed using steel construction and composite board wall
Assembling, the advantages that with short construction period, energy-conserving and environment-protective, is used in 35-110kV intelligent substations for nearly 2 years by large-scale popularization
In construction.At the same time, the lightning protection of the transforming plant assembly type building lightning protection form special as one is concerned.
1st, several frequently seen building lightning protection form
Lightning protection earthing system is built mainly based on direct striking thunder prevention and the intrusion of lightning protection electric wave, so that it is guaranteed that building, equipment
With the safety of personnel, common building lightning protection form has following 3 kinds：
(1) civil buildings (frame structure)：Independent reinforcing bar downlead+foundation grounding net in roof lighting proof strip+post.It is civilian to build
Middle frame structure is built using more, roof sets lighting proof strip, and independent reinforcing bar is as downlead using in post, due to civil buildings
Grounded screen based on earthed system, sets breaking of contact case when downlead is connected with foundation grounding net, the general concealed installation of breaking of contact case exists
Within the walls, the measurement of grounding resistance is facilitated.
(2) civil buildings (steel construction)：Roof lighting proof strip+H profile steel downlead+foundation grounding net.Part civil buildings are adopted
With steel structural form, steel building lightning protection uses steel construction (H profile steel) conduct when under roof setting lighting proof strip, lighting proof strip draw
Downlead, due to grounded screen based on the earthed system of civil buildings, provided according to specification, during using foundation grounding net, steel knot
Structure downlead is not provided with breaking of contact, and steel construction is directly welded by band steel to be connected with foundation grounding net, realizes that roof lighting proof strip draws
Offline reliable ground.
(3) traditional transformer station's building (tower structure)：Roof lighting proof strip+independent reinforcing bar downlead+foundation grounding net.Pass
The building of system transformer station is generally tower structure, is built using armored concrete, roof lighting proof strip typically utilizes independent steel
Muscle is as downlead, and downlead is away from breaking of contact case is set at ground 0.3-1.8 rice, breaking of contact case is typically using concealed installation in wall
Interior, lighting proof strip downlead is connected by breaking of contact with horizontal grounding net, realizes the reliable ground of roof lighting proof strip.
2nd, intelligent substation assembled architecture lightning protection form
In novel intelligent power station, assembled architecture lightning protection form uses：Roof lighting proof strip+H profile steel downlead+level connects
Earth mat.There is some difference with above 3 kinds of common lightning protection forms for this building lightning protection form, belongs to a kind of special
Building lightning protection form, assembled architecture built using steel construction and combined wall board, roof lighting proof strip draw under when use steel
Structure H profile steel, according to code requirement, uses as downlead, but because System in Substation is using horizontal grounding net ground connection
When horizontal grounding net is grounded, downlead needs to install breaking of contact additional.Following table is 4 kinds of building lightning protection form contrasts：
4 kinds of building lightning protection form contrast tables
3rd, there is problem in transforming plant assembly type building lightning protection earthing system
In conventional frame formula structural construction, breaking of contact case takes concealed installation mode, and scheme of installation is shown in Fig. 1, but new
In assembled architecture, using traditional breaking of contact case concealed installation when in steel construction and combined wall board (scheme of installation is shown in Fig. 2), mainly
Following 4 be present：
The down conductor pad of H profile steel is located at web, when pad is connected with old-fashioned breaking of contact case, between the two
Connection band steel to be bent by many places, and part band steel is outside the combined wall, complicated construction technique, unsightly；Installation
Schematic diagram is shown in Fig. 2.
There is hidden danger in old-fashioned breaking of contact case concealed installation, easily loosen, cause upper end connection flat in combined wall board wall when fixed
Steel rocks, and potential safety hazard be present；Scheme of installation is shown in Fig. 2.
There are Insulation Problems in old-fashioned breaking of contact tank shell material, easily cause steel plate shell between steel plate, with earth lead
Misconnection between body and earth conductor, it can not be disconnected so as to cause to connect downlead and grounded screen.
Multilayer antirust paint is scribbled when H profile steel is dispatched from the factory, with being made during old-fashioned breaking of contact case Site Welding, it is necessary to destroy japanning of dispatching from the factory
Into second painting and the problems such as welding is unreliable be present.
Utility model content
The purpose of this utility model is to be directed to the deficiency mentioned in background technology and provide a kind of new disconnecting output stacker
Mounting structure, it is possible to achieve the reliable ground of transforming plant assembly type building roof lightning-protection system, construction technology is simple, safely may be used
Lean on.
To achieve these goals, technical solution adopted in the utility model is：
A kind of transforming plant assembly type builds the new breaking of contact tank mounting structure of lightning protection, including H profile steel, assembled wallboard connection
