Embodiment Construction

[0012] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] The installation and implementation steps of the present invention are as follows:

[0014] (1) On the side wall near the power transmission line 4 or the entire wall (including the roof), the metal wires are fixed on the wall or embedded between the wall bricks to form a shielding net 1, such as figure 1 shown. The metal wire used in the shielding net 1 is a tinned copper braid TZX-15 with a width of 9mm.

[0015] (2) Lead the metal doors and windows on the wall and metal door and window frames 3 to the shielding net 1 with metal wires to make them in good contact. The metal wires used are 9mm wide tinned copper braid TZX-15 for soft connection.

[0016] (3) Select 4 to 6 points at equal intervals on the shielding net 1 at the bottom of the wall where the shielding net is installed, and lead the g...

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 [0001] The invention belongs to the field of electromagnetic environment of power transmission and transformation projects, in particular to a device for reducing the induced electricity of houses around power transmission and transformation facilities by adopting shielding measures. Background technique [0002] With the continuous development of China's electric power industry, in order to promote efficient use of energy, alleviate environmental pressure, and rationally allocate resources, the State Grid Corporation of China has formulated a power grid planning goal of "accelerating the construction of UHV as the backbone grid and coordinated development of power grids at all levels" . However, due to the public's misunderstanding of the electromagnetic environment of power transmission and transformation projects, incidents of obstructing the construction of power transmission and transformation projects have occurred from time to time, resulting in the co...
