Abstract
The utility model discloses a transformer substation uses earth connection, including universal joint, earth connection tie point and insulating bar, insulating bar is the cylinder structure, universal joint sets up in insulating bar's upper end, the earth connection tie point sets up the one end of being close to universal joint on insulating bar for fixed earthed busbar, the utility model discloses different shape generating lines can be satisfied and earthing device's demand is installed to the security that has improved operation personnel and equipment, simple structure, easily operation, flexible, portable, suitability are high.
Description
Technical field
The utility model relates to station instrument, is specifically related to a kind of transformer station earth connection.
Background technology
Along with the high speed development in epoch, living standards of the people improve constantly, and the power consumption in city is also increasing gradually, improve reliability, the economy of operation of power networks, become the primary liability of electric power people; In order to effectively utilize conductor material and make it heat radiation in transformer station, often make flute profile or rhombus at heavy current busbar, also have circle, but cause many inconvenient parts when interruption maintenance installing earth connection to like this our maintainer; The shape of connecting wires when installing because of bus of conventional transformer station's use is different, sometimes just can not meet our maintenance repair demand, cannot carry out good ground connection installing to it; Bring potential safety hazard can to like this our maintainer, also potential safety hazard is existed to our operation of electrical network; The junction of the conventional earth connection conductor wire end used is all single, cannot meet the ground connection installing of difformity bus.
Utility model content
The utility model provides a kind of transformer station's earth connection meeting difformity bus installing earthing device demand.
The technical solution adopted in the utility model is: a kind of transformer station earth connection, comprises universal joint, earth connection tie point and insulating bar; Described insulating bar is cylindrical structure; Described universal joint is arranged at the upper end of insulating bar; Described earth connection tie point is arranged at the one end near universal joint on insulating bar, for dead earth bus.
Further, described universal joint top is provided with and has externally threaded screw rod.
Further, described earth connection tie point is the screw be arranged on insulating bar.
The beneficial effects of the utility model are:
(1) the utility model is provided with universal joint, can meet the demand of difformity bus installing earthing device;
(2) the utility model improves the fail safe of operating personnel and equipment, avoids the security incident of generation personnel and equipment;
(3) the utility model structure simple, be easy to operation, flexible, be easy to carry, applicability is high.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is earth connection tie point structural representation in the utility model.
In figure: 1-universal joint, 2-earth connection tie point, 3-insulating bar.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of transformer station earth connection, comprises universal joint 1, earth connection tie point 2 and insulating bar 3; Described insulating bar 3 is cylindrical structure; Described universal joint 1 is arranged at the upper end of insulating bar 3; Described earth connection tie point 2 is arranged at the one end near universal joint 1 on insulating bar 3, for dead earth bus.
Described universal joint 1 top is provided with has externally threaded screw rod; This structural design facilitates the fixing of earth connection.
Described earth connection tie point 2 is for being arranged at the screw on insulating bar 3; This structural design can by the degree of tightness of adjustment screw, and the convenient bus for different model and size is fixed.
During use, difform bus can carry out ground connection by means of only replacing universal joint 1, is fixed by bus by earth connection tie point 2, does not need to change earth connection according to the model of bus, has saved cost, simultaneously also easy to use.
This invention simplicity of design of the utility model, easy to operate, flexible, safe and reliable; This device reduces the potential safety hazard of operating personnel and equipment, avoids generation personnel and device security accident; Thus reach to be in operation and user is carried out to the object of safe and reliable power supply, meanwhile not only create good economic benefit, also create the situation of social benefit doulbe-sides' victory; When the utility model can install earthing device in actual station operation, better guarantee earth terminal ground connection is good, greatly reduce the potential safety hazard of operating personnel, while reduction operating personnel labour intensity, also ensure the safe operation of electrical network, create the doulbe-sides' victory of economic benefit and social benefit.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
