Description
Technical field
The utility model relates to a kind of connector, relates in particular to a kind of connector of three-phase integrated formula cable joint.
Background technology
In the electric power system, long distance power transmission adopts the three-phase three-wire system mode.Cable end connector (being commonly called as the integral type casing seat) is as the bridge that connects between high-tension cable and the panel switches, and it mainly is made up of conductive copper core and insulating material of being wrapped in around it.The cable joint of Shi Yonging in the market mainly contains through type, " π " Y joint, front and adds the first-class version in back, and straight-through structure is compared with back two kinds of structures, its autgmentability, range of application, installs and uses aspect such as convenience and all has obvious deficiency.
High-tension cable is connected with connector by cable joint, at present, some air insualtion high voltage switchgear, owing to be subjected to the influence of connector mounting means, product can only adopt the through type cable joint in the selection of cable joint, though its system configuration has advantage, have wide range of applications, but adopt the through type cable joint still to have following significant deficiency: 1. extremely difficult when cable end is installed at the scene, be not easy to construction, not hommization is unfavorable for maintenance; 2. through type cable joint volume is bigger, can strengthen the cabinet volume, reduces the competitive advantage of product; 3. adopt the through type cable joint, be not easy to inlet wire and install lightning arrester additional, also be difficult to simultaneously solve the problem of paired cable into and out of line, the scope of application of product is narrow, makes product not possess tangible competitive advantage on market.
Cause the main cause of this phenomenon to be to be subjected to air insualtion high voltage switch apparatus system structure and air-insulated the influence, in the switchgear cabinet, be difficult for connector base (end of stube cable joint) is led, if lead, can enlarge markedly the volume of switchgear so, make product lose market competition advantage, therefore, can only be arranged as the connector base perpendicular to the groundly, that is: connector conductive copper core is perpendicular to the ground.
At present, inflation cabinet in the power switchgear, the main SF6 gas that adopts is as insulating material, therefore, in the inflation cabinet, connector is led than being easier to, can obviously not increase the cabinet volume yet, but adopting SF6 inflation cabinet also to have following deficiency: 1.SF6 simultaneously is one of six kinds of greenhouse gas finding at present, owing to use, miscarriage or it is not reclaimed by correct method, Regeneration Treatment, the poisonous analyte that causes SF6 gas and produce under the high-temperature electric arc effect is discharged in the atmosphere, the environment of depending on for existence to the mankind brings pollution and destruction, gives the normal operation and the healthy adverse effect of bringing of people of electric equipment simultaneously.2. the apparatus body sealing goes wrong gas is seriously leaked, and causes a serious accident.3. in price, the price of SF6 inflation cabinet generally make the air insulation switchgear 1.6-2.5 doubly.
Analysis by above three aspects can draw the air insualtion high voltage switchgear and still have very big development prospect with respect to the following switchgear of SF6 gas inflated cabinet, particularly 110kV.
Air insualtion high voltage switch product systems structure has advantage, has wide market prospects, owing to can only select to adopt the through type cable joint, makes entire product lose competitive advantage, and therefore developing a novel connector becomes urgent problem.
The utility model content
Technique effect of the present utility model can overcome above-mentioned defective, and a kind of cable joint connector is provided, and its cable end is easy for installation, autgmentability is strong.
For achieving the above object, the utility model adopts following technical scheme: it comprises fixed head, the affixed straight coupling of fixed head upside, the affixed copper core guiding of fixed head downside insulating barrier, the side of copper core guiding insulating barrier is provided with cable joint and connects base, and the copper core runs through and is connected with straight coupling after cable joint connects base, copper core guiding insulating barrier.
Straight coupling is perpendicular to the fixed head setting, and joint connects base and is parallel to the fixed head setting.
Change the connector structure, the connector base is led, after the connector installation, the copper core of the conduction of its stube cable joint by perpendicular to the ground change into parallel to the ground, consider the small and exquisite characteristics that more possess competitive advantage of high voltage switchgear volume, three individual event cable joint connectors are designed to three-phase integrated formula cable joint connector, and its overall structure still has the volume advantage after like this connector base being led, and does not influence the volume of whole high voltage switchgear.Adopt three-phase integrated formula cable joint connector, make product in the selection of cable joint, no longer be subjected to select to use the restriction of straight-through structure, can select " π " Y joint, front to add the first-class version in back, so successfully solve the major defect that the said goods exists, make product have competitive advantage in market.
Fixed head is provided with fixing hole.
The utility model carries out perfect according to the defective that the problems referred to above are brought to the autgmentability of mounting means, structure and the cable joint of connector, develop a kind of novel three-phase integrated formula cable joint connector, for solve the air insulation switchgear because of be subjected to system configuration and air-insulated influence to be difficult in cabinet the connector base led important breakthrough is provided, and successfully solve the significant deficiency of above-mentioned existence.
No matter the utility model all has marked improvement in structure and realization technology, and has produced handy and practical effect, thus practical more and have the extensive value of industry, be the new design of a kind of novelty, marked improvement.
