Abstract
The invention discloses a method for decoupling the grounding grid distance of a communication bureau station in case of dangerous influence to the communication bureau station caused by strong currents. The method comprises the following steps of: 1, when the foundation of a communication bureau station building is constructed, constructing the foundation which is far away from one side of a high-voltage power transmission system grounding grid by common concrete building material, constructing the foundation of another three sides by water-poor concrete building material, and externally paving asphalt to improve insulation; and 2, setting a grounding bar at one side which is far away from the high-voltage power transmission system grounding grid within the communication bureau station, wherein a work ground, a protecting ground and an anti-lightning ground of the equipment within the bureau station are all electrically connected with the grounding bar to form integrated grounding, and electrically connecting the grounding bar with a reinforcing steel bar within the foundation of one side of the communication bureau station which is far away from the high-voltage power transmission system grounding grid. The method has the advantage that under the condition that the physical distance between the high-voltage power transmission system grounding grid and the communication bureau station is not prolonged, the aim for prolonging the distance between two grounding grids can be achieved, so that the addresses of the communication bureau station and the high-voltage power transmission system are more flexible to select, and the addresses selecting range can be enlarged.
Description
Technical field
The present invention relates to communications office site's earth mat apart from uncoupling method, when especially relating to forceful electric power to communications office site's dangerous influence, communications office site's earth mat is apart from uncoupling method.
Background technology
Along with the fast development of communication and two important system of electric power, near the situation that communications office site is positioned at high voltage transmission line and high voltage substation is more and more general, and when both close together, high voltage power transmisson system can produce security implication to the people in communications office site and equipment.In the situation of high voltage power transmisson system generation earth fault, can produce huge moment earth potential liter on the net on high voltage power transmisson system ground, and induce high potential by the Resistive Coupling of the earth on the net on the ground of communications office site.This high potential will produce dangerous influence to staff and the communication equipment of communications office site.The method that in the past prevented this dangerous influence can only adopt distance to go the lotus root method, and the distance that namely increases communications office site and high voltage power transmisson system reduces high voltage power transmisson system to the dangerous influence of communications office site.This method major defect is the addressing scope that has limited communications office site, makes a lot of positions can not build communications office site.
Summary of the invention
When the object of the invention is to provide a kind of forceful electric power to communications office site's dangerous influence, communications office site's earth mat is apart from uncoupling method.This method reaches the purpose that increases the Resistive Coupling distance under the condition that does not increase physical distance, and then eliminates the earth potential liter to the impact of communications office site.
For achieving the above object, the present invention takes following technical proposals:
Forceful electric power of the present invention is communications office site's earth mat distance method of uncoupling during to communications office site's dangerous influence, comprises the steps:
When one, construct in the communications office site building foundation, use the construction of normal concrete construction material away from the basis of high voltage power transmisson system ground network one side, and the construction of water-proof concrete construction material is used on the basis of other three sides, and external application pitch is with the increase insulation;
Two, away from high voltage power transmisson system ground network one side, earthing bar is set in communications office site; the place of working of communication bureau's station equipment, protection ground, lightning proof ground all are electrically connected the formation joint grounding with described earthing bar, then this earthing bar and communications office site are electrically connected away from the reinforcing bar in high voltage power transmisson system ground network one side group plinth.
The invention has the advantages that with the earthing bar in communications office site be arranged on away from high voltage power transmisson system ground network one side and with the building foundation of this side in the reinforcing bar electrical connection, and adopt water-proof concretes construction and external application pitch to increase insulation apart from high voltage power transmisson system ground network nearer other three side building foundations.Like this, in the situation that do not increase high voltage power transmisson system ground network and communications office site's physical distance, reach the purpose that increases distance between both ground networks, increased Resistive Coupling distance between the two, and then reduced the dangerous influence of high voltage power transmisson system to communications office site.Make the addressing of communications office site and high voltage power transmisson system become more flexible, increased the scope of its addressing.
Description of drawings
Fig. 1 is according to the communications office site of the inventive method building and the layout schematic diagram between high voltage power transmisson system.
Embodiment
As shown in Figure 1, forceful electric power of the present invention is communications office site's earth mat distance method of uncoupling during to communications office site's dangerous influence, comprises the steps:
When one, construct in communications office site 1 building foundation, the construction of normal concrete construction material is used on basis 4 away from high voltage power transmisson system 2 ground network 3 one sides, and the construction of water-proof concrete construction material is used on the basis 5,6 of other three sides, 7, and external application pitch is to increase insulation;
Two, away from high voltage power transmisson system 2 ground network 3 one sides, earthing bar 8 is set in communications office site 1; the place of working of the interior equipment 9 of communications office site 1, protection ground, lightning proof ground all consist of joint groundings with described earthing bar 8 electrical connections, then this earthing bar 8 are electrically connected away from the interior reinforcing bar 10 of high voltage power transmisson system 2 ground network 3 one side group plinth 4 with communications office site 1.
