Abstract
The utility model discloses a plug-in type guide positioning grounding structure of a breaker handcart. The structure comprises a guide grounding rod installed on a switch cabinet partition and a guide grounding ring installed at a position corresponding to a breaker handcart chassis. The guide grounding ring is mutually cooperated with the guide grounding rod. The guide grounding ring is connected with a plum blossom contact. The plum blossom contact is mutually and cooperatively contacted with the guide grounding rod. According to the structure of the utility model, through erecting a guide grounding device (the guide grounding rod, the guide grounding ring and the plum blossom contact) between the switch cabinet and the breaker handcart, problems of poor contact of a three-phase conductive contact and imperfect earth are solved. The structure is simple and operation is convenient. The structure is suitable for the moveable switch cabinet.
Description
Technical field
The utility model relates to a kind of earthing device, particularly relates to a kind of circuit breaker cart plug-in type guide-localization ground structure.
Background technology
Before the utility model proposes, when circuit breaker cart is connected with switch cubicle, all be to aim at the three-phase conductive contact by the restriction of handcart track generally, but this alignment so is very inaccurate, in case slightly there is deviation will cause the loose contact of three-phase conductive contact.Simultaneously, the ground connection of circuit breaker cart generally all is to adopt the undersurface of bottom disc at circuit breaker cart to add grounding wafer, in case this sliding contact earthing mode exists insufficient pressure will cause the problem of imperfect earth.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, provides a kind of simple in structure and connect reliable circuit breaker cart plug-in type guide-localization ground structure.
In order to realize above purpose, a kind of circuit breaker cart plug-in type guide-localization ground structure that the utility model provides, comprise: be installed in the guiding earth brace on the switch cubicle dividing plate, be installed in the guiding ground loop of circuit breaker cart chassis correspondence position, guiding ground loop and described guiding earth brace cooperatively interact; Be connected with Mume flower contact on the described guiding ground loop, Mume flower contact cooperatively interacts with described guiding earth brace and contacts.By between switch cubicle and circuit breaker cart, setting up the guiding earthing device, solved the problem of the loose contact of three-phase conductive contact and imperfect earth, simple in structure, easy to operate.
In such scheme, described Mume flower contact comprises contact, with contact centring ring and the contact circle spring of positioning port, and described contact is inserted in the positioning port of described contact centring ring, and described contact circle spring is set with on the described contact; Described guiding ground loop is provided with the bayonet socket for the described Mume flower contact of clamping, and position corresponding on the contact of described Mume flower contact is provided with the clamp that matches with described bayonet socket, and described guiding ground loop is by described bayonet socket and clamp and described Mume flower contact clamping.Certainly, guiding ground loop and Mume flower contact also can adopt other connected modes.
In such scheme, the quantity of described guiding earth brace is at least 2, and the quantity of described guiding ground loop and Mume flower contact is identical with the quantity of guiding earth brace.
The utility model has solved the problem of the loose contact of three-phase conductive contact and imperfect earth by set up guiding earthing device (guiding earth brace, guiding ground loop and Mume flower contact) between switch cubicle and circuit breaker cart, and is simple in structure, easy to operate.
The utility model is compared with the prior art, and shows that fully its superiority is: simple in structure, easy to operate and connection reliability is good etc.
