Abstract
The invention discloses a breaker bracket, which comprises a concrete wire rod. The periphery of a reinforcing mesh exposed out of the upper end of the concrete wire rod is electrically connected with a conductive metal ring. The upper surface of the conductive metal ring is electrically connected with an upper installation plate. The lower surface of the upper installation plate is electrically connected with a grounded wire of which the shape is in fit with the shapes of the conductive metal ring and the concrete wire rod. The grounded wire is electrically connected with the conductive metal ring. The lower end of the grounded wire is grounded. The lower end of the concrete wire rod is provided with a lower installation plate. The lower installation plate is fixed on a base. The shape of the grounded wire is in fit with the shapes of the conductive metal ring and the concrete wire rod and is grounded reliably. Meanwhile, the grounded wire is electrically connected and contacted with the conductive metal ring, so that the contact area between the grounded wire and the conductive metal ring is increased, the current-carrying capacity of the grounded wire is improved, and the abnormal current can be rapidly dredged. The reinforcing mesh is connected with an upper connection plate and a lower connection plate to form another grounded circuit so as to form a double grounded mode together with the grounded wire, and thus, the grounded reliability is improved and the potential safety hazard is eliminated.
Description
Technical field
The present invention relates to a kind of circuit breaker cradle.
Background technology
Electric equipment can cause its shell to have certain static because insulation property are bad or environment for use is moist, when serious electric shock accidents can take place.For fear of accident occurring, can connect a lead ground connection on the metal shell of electric equipment is earth connection, and earth connection can import to the earth to static and discharges when electric leakage takes place electric equipment.At present, the circuit breaker mounting bracket has the integrative-structure of traditional armored concrete line bar and angle steel weldering system.The integrative-structure of angle steel weldering system is heavy, can't dismantle, be inconvenient to install, and the cost of transportation height, and easily leak out of doors and corrosion.Armored concrete line bar simple installation, detachable moving, uses more flexible, but earth connection is a ground connection vertically downward from the mount pad of upper end, earth point is single, ground connection is unreliable, is prone to the phenomenon of earth connection disconnection, has potential safety hazard.
The utility model content
The purpose of this invention is to provide the circuit breaker cradle that a kind of ground connection is reliable, ampacity is big.
For achieving the above object, technical scheme of the present invention is: circuit breaker cradle, comprise concrete line bar, and the bar-mat reinforcement periphery of the described concrete line bar naked leakage in upper end is electrically connected with the conducting metal circle, is electrically connected above the conducting metal circle and is provided with upper mounting plate; Be electrically connected with the earth connection that adapts with conducting metal circle and concrete line bar profile below the upper mounting plate, described earth connection is electrically connected with the conducting metal circle, earth connection lower end ground connection; Concrete line bar lower end is provided with lower installation board, and lower installation board is fixed on the seat of basis.
Described lower installation board is electrically connected with bar-mat reinforcement.
Described conducting metal circle constitutes by being welded on the outer steel plate of bar-mat reinforcement.
Described earth connection adopts Type of Welding to be connected with upper mounting plate and conducting metal circle.
Described earth connection is the ground connection band iron.
Described lower installation board is installed on the seat of basis by threaded connector.
The threaded connector of described lower installation board is provided with the thermoplastic protective cap outward.
Advantage of the present invention:
1, earth connection that connects on the upper mounting plate and conducting metal circle and concrete line bar profile adapt, and ground connection is reliable, are not prone to earth connection and disconnect phenomenon; Simultaneously, earth connection is electrically connected with the conducting metal circle and contacts, and has increased the contact area of earth connection and conducting metal circle, and it is big to improve the earth connection ampacity, can dredge fault current fast; Bar-mat reinforcement links to each other with lower connecting plate with upper junction plate and forms another grounded circuit, forms two ground connection with earth connection, improves the ground connection reliability, eliminates safe hidden trouble.
2, adopt Type of Welding to realize being electrically connected, both guaranteed good electrical conductivity, improve bonding strength again.
3, earth connection adopts the ground connection band iron, and band iron and conducting metal circle contact area are big, and ampacity is big, and the intensity height, and long service life is with low cost.
4, threaded connector is provided with the thermoplastic protective cap, prevents that the threaded connector corrosion from damaging, and guarantees the reliability of connection, increases the service life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Circuit breaker cradle as shown in Figure 1, it comprises columniform concrete line bar 1, the inside of concrete line bar 1 is provided with bar-mat reinforcement 11, the naked leakage in the upper end of bar-mat reinforcement 11 is in concrete line bar 1 outside, be provided with conducting metal circle 2 bar-mat reinforcement 11 peripheral electrical connections, be electrically connected above the conducting metal circle 2 and be provided with upper mounting plate 3, upper mounting plate 3 is used to install electric equipment.Lower end at concrete line bar 1 is provided with lower installation board 5, and lower installation board 5 is fixed on the basis seat 6 by threaded connector 7 with bar-mat reinforcement 11 lower ends welding, lower installation board 5.Conducting metal circle 2 is formed by welded steel plate, and the material of upper mounting plate 3 is a steel plate.Below upper mounting plate 3, be electrically connected with earth connection 4, earth connection 4 extends downwards and the profile of conducting metal circle 2 and concrete line bar 1 adapts, be that earth connection 4 is welded on the surface of conducting metal circle 2, by being close on the surface of concrete line bar 1 the lower end ground connection of earth connection 4 after the bending.For preventing that threaded connector 7 corrosions from damaging, on threaded connector 7, be provided with thermoplastic protective cap 8, guarantee concrete line bar 1 secure fixation.Described earth connection 4 is the ground connection band iron, can effectively increase the contact area with conducting metal circle 2, increases the ampacity of earth connection 4.
In the present embodiment, Type of Welding is all adopted in described electrical connection, has both guaranteed good electrical conductivity, improves bonding strength again.
