Abstract
The utility model relates to an auxiliary ground ring for low-voltage grounding. The auxiliary ground ring is characterized in that: the auxiliary ground ring comprises a copper rod (3), a wiring ring (1) is arranged on one end of the copper rod (3), the other end of the copper rod (3) is provided with a threaded hole (4), and moreover, the middle of the copper rod (3) is wrapped by an insulating layer (2). The auxiliary ground ring has the following advantages: (1) ground wires on an air circuit breaker and a low-voltage insulated line can be in good contact with line equipment, and thereby potential safety hazards in work are eliminated; (2) the auxiliary ground ring is small and low in cost, and is easy to fabricate and operate and convenient to carry, and the used space is small, so that the auxiliary ground ring cannot be limited by the line equipment; (3) workers can more conveniently and rapidly mount low-voltage ground wires under special conditions, and man-hour and labor can be saved.
Description
Technical field
The utility model relates to the earthy auxiliary earth ring of a kind of low pressure.
Background technology
The low-pressure side in distribution transformer platform district (be called for short and become platform) all adopts air switch to control at present; When working on the transformer stand or on the low-voltage circuit of contiguous change platform; Need on low-voltage air switch, install earth connection; And the terminal block of low-voltage air switch gap ratio each other is nearer, and installing low pressure earth connection is very inconvenient.Owing to become the limitation in platform summary table case space, some is local even have the situation that earth connection can't be installed, and causes the operation of part power cut construction not have safety assurance, exists certain potential safety hazard in addition.Low-voltage circuit adopts aerial insulated wires at present in addition; The low pressure earth connection can only be selected to be installed on the parallel groove clamp during maintenance construction; Yet often exist between the eave tile of low pressure earth connection and the parallel groove clamp and be connected illusive phenomenon; Circuit also exists certain potential safety hazard as long as be easy to come off once swinging gently.
The utility model content
The purpose of the utility model provides the earthy auxiliary earth ring of a kind of low pressure, adopts this auxiliary earth ring to make to contact between low-voltage air switch and low-voltage insulation circuit and the corresponding earth connection good.
The earthy auxiliary earth ring of a kind of low pressure, its special feature is: comprise a bronze medal bar, be provided with the wiring ring at an end of this copper bar, and have screwed hole at the other end of this copper bar, and be covered with insulating barrier at this copper bar tundish.
Wherein insulating barrier adopts thermoplastic tube.
Wherein the wiring ring is three square rings or annulus.
The beneficial effect of the utility model is: 1, realized between earth connection on low-voltage air switch and the low-voltage insulation circuit and line facility, contacting good, eliminated the potential safety hazard in the work; 2, volume is little, and is simple for production, with low cost, easy to carry, simple to operate, thus the little restriction that does not receive line facility of usage space; 3, it is more convenient to make the staff under specific condition, install the low pressure earth connection, and promptly the saving of labor is laborsaving again.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model is the earthy auxiliary earth ring of a kind of low pressure, comprises a bronze medal bar 3; End at this copper bar 3 is provided with wiring ring 1, and has screwed hole 4 at the other end of this copper bar 3, and is covered with insulating barrier 2 at these copper bar 3 tundish; Insulating barrier 2 specifically can adopt thermoplastic tube; And wiring ring 1 is identical with copper bar 3 materials, can be welded on the copper bar 3 or directly with copper bar 3 one ends distortions as wiring ring 1, wiring ring 1 can adopt three square rings or toroidal.
Screwed hole 4 with copper bar 3 one ends during use is screwed on the corresponding binding post; Binding post is generally and has externally threaded bolt; Just the screwed hole 4 with copper bar 3 one ends cooperates; With wiring ring 1 place of U type parallel groove clamp insertion copper bar 3 other ends, under action of gravity, can form firm contact-making surface after tightening.Extract U type parallel groove clamp after finishing using, screw off copper bar 3 and get final product.
Claims (3)
1. earthy auxiliary earth ring of low pressure is characterized in that: comprise a bronze medal bar (3), be provided with wiring ring (1) at an end of this copper bar (3), and have screwed hole (4) at the other end of this copper bar (3), and be covered with insulating barrier (2) at this copper bar (3) tundish.
2. the earthy auxiliary earth ring of low pressure as claimed in claim 1 is characterized in that: wherein insulating barrier (2) adopts thermoplastic tube.
