Description
Technical field
The present invention relates to technical field of electric power construction, be specifically related to a kind of permanent embedded grounding body of urban distribution network and
Its construction method.
Background technique
10 kilovolts of city high voltage distribution network, 0.4 kilovolt of low-voltage network are distributed in town road two sides, road two more at present
Dypass face during carrying out urban distribution network maintenance, repairing, is needing to install ground line by pitch, hardening of cement
When, exist and nowhere install the trying situation that ground terminal, grounding pin can not be driven underground, can waste the more time looks for properly
Earthing position, greatly reduce working efficiency, got to grounding pin by force below concrete even if finding gap reluctantly, road
Lower section is mixed with building waste, rubble, and soil resistivity seriously exceeds standard value, and ground resistance is unqualified, seriously reduces ground connection
The earthing effect of line makes the safeguard protection performance of ground line have a greatly reduced quality, and finally influences whether that maintenance and repair personnel's counnter attack are sent
Electricity safety and reduce working efficiency.
Summary of the invention
To solve the problem of that web area road hardening shortage in city suitably beats grounding pin, the invention proposes a kind of pre-buried
Grounding body and its construction method, ground connection is functional, and is embedded to underground in advance, easy to use and reliable, improves working efficiency and guarantor
Hinder the ground protection safety of construction personnel.
The present invention provides a kind of permanent embedded grounding body of urban distribution network, and 4 angles of grounded screen (5) are with connecting 4 piece-root graftings
4 sides of needle (6), grounded screen (5) connect 4 earthing modules (7) by band iron, and the other end of 4 earthing modules (7) passes through flat
Iron links together, and online (3) are drawn in grounded screen (5) connection, draws online (3) and extends to the part of ground (4) or more and passes through bolt
It is fixed on electric pole (1), the upper end for drawing online (3) is provided with Wiring port (2), and hole (201) are arranged on Wiring port (2)
With gap (202).Earthing module (7) can preferably compensate soil resistivity, and lower end is equivalent to resistance using band iron connection
Parallel connection keeps the effect of earthing module more preferable, and hole (201) and gap (202) are used to install the ground terminal of ground line, using bolt
Bolt can be caught in gap (202) interior tightening nuts when connection, and do not have to be pierced by bolt, therefore even if bolt from the back side
The too long installation for nor affecting on ground terminal of length.
The side length of grounded screen (5) is 1-1.2m, and grounding pin (6) length is 1.2-1.3m, the connection of earthing module (7) lower end
Height of the band iron apart from grounded screen (5) is 70-80cm, and height of the Wiring port (2) apart from ground (4) is 1.4-1.6m.
A kind of construction method of the permanent embedded grounding body of 10 kilovolts of urban distribution networks: in city 10 kilovolts of net, 0.4 kilovolt match
Lower section of the electric line equipped with ground connection link, deep-cuts to ground (4) following 2.2-2.3m, by earthing module (7) and its company of lower end
Band iron embedment, the connection band iron welding of earthing module (7) and its lower end are connect, and does preservative treatment, by earthing module (7) upper end
Band iron is welded in 4 sides of grounded screen (5), and does preservative treatment；Grounded screen (5) is seated to away from ground (4) following 1.5m, In
4 grounding pins (6) are squeezed into the position at 4 angles of grounded screen (5), and grounding pin (6) length is 1.2-1.3m, by grounding pin (6)
4 welded corner joints of upper end and grounded screen (5), and do preservative treatment；According to the distance between grounded screen (5) and electric pole (1), it is being grounded
The band iron of one side of net (5) or a welded corner joint appropriate length will draw online (3) and be bolted on electricity as online (3) are drawn
On bar (1), and Wiring port (2) are welded in the upper end for drawing online (3).
The side length of grounded screen (5) is 1-1.2m, and height of the Wiring port (2) apart from ground (4) is 1.4-1.6m, grounding pin
(6) bottom is apart from ground (4) 2.7-2.8m.
Ground connection is carried out in advance in newly-built, transformation project in lower section of the 10 KV distribution route of net equipped with ground connection link in city
Net, pre-buried good grounding body have stayed grounding ports by the ground connection band iron connected on ground, can examine to route
It repairs, repair and directly used when need to be grounded.
The beneficial effects of the present invention are:
The depth of embedded grounding body hereinafter, solder joint robust, and has done preservative treatment in 2.5m；Wiring port is located at electricity nearby
On bar, the ground connection band iron of national standard is used；Ground resistance is below 10 Europe.The design is stayed on ground by the ground connection band iron connected
Good grounding ports can directly be used when being overhauled to route, repairing and need to be grounded；
For improving city net road hardening regional power grid interruption maintenance, during repairing hanging earthing conductor efficiency clearly, can
120% or so are improved, saves the repair time, while the embedded body because doing in advance is smaller compared with grounding pin ground resistance, the effect of ground connection
Higher with the security performance of ground connection, the grounding body structure is simple, meets the requirements of the standard, and is suitable for being widely applied in city web area.
