The cable ring main unit emergency overhaul apparatus is characterized in that the box body is a totally enclosed box body; the temporary connecting buses are in a totally enclosed state in the box body; enclosed insulation is realized with air taken as insulation medium; and a high-voltage induction type charged display apparatus is disposed inside the box body. The cable ring main unit emergency overhaul apparatus uses air for bus totally enclosed insulation, realizes load current distribution in the method of hard connection of buses and busbars, is characterized by simple structure and convenient operation and maintenance, has the high-voltage induction type charged display apparatus, realizes charged display and locking when the box body is not opened, and thus facilitates the overhaul.
Description
Technical field
The utility model relates to a kind of apparatus for examination and repair of electric power system, relates in particular to a kind of distribution case change for the cable ring-system cabinet, the apparatus for examination and repair of ring main unit.Be mainly used in the cable ring-system cabinet when breaking down, carry out emergency service.
Background technology
Along with the continuous propelling of Chinese Urbanization, the cable rate of distribution in the city is also improving constantly, and the use of cable ring-system equipment is also more and more, and these looped network equipment various problems will occur after using through certain hour; Cable ring-system cabinet (claiming distribution box again) is the equipment that constant weight is wanted in the electric power system, the problem of recently relevant ring main unit constantly occurs, after occurring, these problems must overhaul processing to fault rapidly, because the existing cable ring main unit is all insulation, the totally-enclosed outdoor equipment that is used for tapping cable branch in the cable line, the cable ring-system cabinet has the advantages that all insulation, full closeding equipment do not have bare spots, no obvious cut-off point, can't apply mechanically the safety measure of original custom when making the line facility maintenance.How the cable ring-system cabinet is overhauled, when guaranteeing equipment dependability, reduce maintenance to user's power failure influence, reduce workload, the power supply reliability of raising system need be carried out the research of distribution maintenance, and this has become the subject matter of present distribution safety inspection.Necessary this is solved.
The utility model content
The purpose of this utility model is to overhaul existing some shortcomings at the existing cable ring main unit, a kind of cable ring-system cabinet apparatus for examination and repair of meeting an urgent need is provided, cable when the emergent apparatus for examination and repair of this cable ring-system cabinet can realize that the cable ring-system cabinet breaks down connects temporarily, can or else do again and realize under the situation of cable joint directly connecting, and the cabinet door is realized the charged demonstration of non-opening.
The technical solution adopted in the utility model is: a kind of cable ring-system cabinet apparatus for examination and repair of meeting an urgent need, comprise a casing, be equipped with in the casing for the interim connection bus of cable, its characteristics are, described casing is totally-enclosed casing, and interim connection bus is in full closeding state in casing, and with air as dielectric, realize the sealing insulation, the charged display unit of high voltage induction formula also is installed in casing.
Further, described interim connection bus adopts one to advance to have more structure, and passes through copper busbar as the electric current split point, and a plurality of users are distributed temporarily.
Further, described copper busbar is installed between two insulators, makes copper busbar and casing form insulation and is connected.
Further, between described copper busbar and two insulators transducer is installed also, for detection of the electrical performance indexes value of copper busbar.
Further, the charged display unit of described high voltage induction formula is the induction type post insulator, is installed in the bus next door, and the induction type post insulator obtains power supply by induction, carries out charged demonstration.
Advantage of the present utility model is:
The utility model adopts air to carry out the totally-enclosed insulation of bus, connects mode firmly with bus and busbar and realizes the load current distribution, has simple in structurely, and operation maintenance is characteristics easily; And the charged display unit of high voltage induction formula arranged, realized casing charged demonstration and locking under the situation of opening not, convenient maintenance.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
From accompanying drawing as can be seen, the utility model relates to the emergent apparatus for examination and repair of a kind of cable ring-system cabinet, comprise a casing 1, be equipped with in the casing 1 for the interim connection bus 2 of cable that its characteristics are, described casing 1 is totally-enclosed casing, interim connection bus 28 is in full closeding state in casing, and with air as dielectric, realize the sealing insulation, at case, the charged display unit 3 of high voltage induction formula also is installed in 1.
Further, described interim connection bus 2 adopts one to advance to have more structure, and passes through copper busbar 4 as the electric current split point, and a plurality of users are distributed temporarily.
Further, described copper busbar 4 is installed between two insulators 5 and 6, makes copper busbar and casing form insulation and is connected.
Further, between described copper busbar 4 and two insulators 5 and 6 transducer 7 is installed also, for detection of the electrical performance indexes value of copper busbar.
Further, the charged display unit 3 of described high voltage induction formula is the induction type post insulator, is installed in interim connection bus 2 next doors, and the induction type post insulator obtains power supply by induction, carries out charged demonstration.
Advantage of the present utility model is:
The utility model adopts air to carry out the totally-enclosed insulation of bus, connects mode firmly with bus and busbar and realizes the load current distribution, has simple in structurely, and operation maintenance is characteristics easily; And the charged display unit of high voltage induction formula arranged, realized casing charged demonstration and locking under the situation of opening not, convenient maintenance.
