Abstract
The invention discloses an induced electricity reducing device for a house around a power transmission and transformation facility. The induced electricity reducing device comprises metal wires and grounding wires fixed on wall surfaces or embedded among wall bricks. The induced electricity reducing device has the advantages that the metal wires on the wall surfaces form a shielding network covering the wall surfaces or roof of the house, the shielding network is in good contact with metal door and windows and metal door and window frames on the wall surfaces, and 4-6 positions, at the bottoms of walls, of the shielding network are grounded; meanwhile, grounding wires are guided from indoor large metal body positions such as a metal clothesline, and induced electricity can be avoided under a weather state in which induced electricity occurs densely.
Description
Technical field
The invention belongs to electromagnetic environment field, specifically a kind of shielding measure that adopts cuts down the faradic device of private residence around power transformating and supplying facility.
Background technology
Along with the development of China electric power industry, in order to advance the efficiency utilization of the energy, alleviate ambient pressure, reasonable disposition resource, State Grid Corporation of China has formulated the Electric Power Network Planning target of " Accelerating The Construction take ultra high voltage as bulk transmission grid, electric network coordination development at different levels ".But because the public exists misunderstanding to the electromagnetic environment of project of transmitting and converting electricity, obstruct the event of project of transmitting and converting electricity construction to happen occasionally, cause partial electric grid to build delayed need for electricity.The electromagnetic environment of AC input transformation engineering mainly comprises power frequency electric field, power frequency magnetic field, radio interference and audible noise four aspects, and power frequency electric field is paid close attention to and one of more Important Problems becoming current research of dispute the most because of the public.
At present, China's residential block power frequency electric field recommends limit value to be 4kV/m, and actual demands of engineering meets this basic demand.For the transmission line built up, improve line levels, change divisural line number, change phase sequence etc. all not easily realizes, and therefore general erection shielding conductor or the method power transformating and supplying facility annex plantation trees of adopting, suppresses induced electricity.And private residence induced electricity indivedual around power transformating and supplying facility is exceeded standard phenomenon, consider economy, can, for this private residence, adopt the measure of earth connection and erection metallic shield net to carry out faradic reduction.
Summary of the invention
For the induced electricity phenomenon that private residence around current power transformating and supplying facility exists, the invention provides private residence induced electricity cutting device around a kind of power transformating and supplying facility, avoid the impact that induced electricity brings resident living.
The present invention is achieved through the following technical solutions: private residence induced electricity cutting device around described power transformating and supplying facility, comprise the plain conductor and earth connection being fixed on metope or be embedded between wall brick, described plain conductor forms the gauze screen covering private residence metope, and described gauze screen passes through ground connection.
Described gauze screen is selected to install near a side wall of transmission line or whole metope, or comprises roof at whole metope and install.
The present invention is also included in the band large-scale metal body place such as metal clothes-line within doors and draws earth connection, avoids the generation of induced electricity phenomenon under the intensive generation state of weather of induced electricity.
Metal door and window, metal door and window framework good contact on described gauze screen and metope.
According to metope size and gauze screen area, can the gauze screen bottom wall select 4 ~ 6 places to draw earth connection.
The invention has the beneficial effects as follows: be private residence induced electricity risk reducing measures around a kind of effective power transformating and supplying facility, be intended to the induced electricity reducing private residence place around power transformating and supplying facility, avoid power transformating and supplying facility produce the impact that induced electricity brings neighbouring resident living, and then reduce the event obstructing project of transmitting and converting electricity to build, accelerate power grid construction, meet user power utilization demand.This apparatus structure is simple, easy to operate, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail.
Installation implementation step of the present invention is as follows:
(1) at a side wall or the whole metope (comprising roof) of close transmission line 4, plain conductor be fixed on metope or be embedded between wall brick, forming gauze screen 1, as shown in Figure 1.The tin-coated copper braid over braid TZX-15 that gauze screen 1 plain conductor used selects 9mm wide.
(2) metal door and window on metope, metal door and window framework 3 to gauze screen 1, are made its good contact with plain conductor lead-in wire.The tin-coated copper braid over braid TZX-15 that plain conductor used selects 9mm wide is flexible coupling.
(3) gauze screen 1 bottom the metope of installing gauze screen selects 4 ~ 6 points at equal intervals, draws earth connection 2 respectively.
(4) earth connection is drawn at the band large-scale metal body place such as metal clothes-line in doors, avoids the generation of induced electricity phenomenon under the intensive generation state of weather of induced electricity.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
