Description
Technical field
Valve pocket is the utility model is related to, in particular, is related to a kind of solid loop-net cabinet.
Background technology
Ring main unit is one group of transmission ＆ distribution electrical equipment (high-tension switch gear) in metal or non-metallic insulation cabinet or done
Into the electrical equipment of assembled compartment ring network power supplying units, its core uses on-load switch and fuse, has structure letter
List, small volume, price are low, can improve the advantages that power supply parameter and performance and power supply safety.It is widely used in city and lived
In the power distribution station and box-type substation of the load centers such as residence cell, skyscraper, large public building, factory and enterprise.Looped network
Refer to ring distribution system, i.e. supply main forms the annular of a closure, and power supply is powered to this ring main, from main line
On pass through the outside distribution of high-voltage switch gear all the way again.Such benefit is that each distribution branch road both can be from its left side
Side main line power taking source, again can be from its right side main line power taking source.When left side, main line is out of order, and just from right side, main line continues for it
To power supply, and when right side main line is out of order, just from left side, main line continues to be powered for it, so, although general supply is
Single service, but obtained for each distribution branch road similar to the material benefit supplied power with double circuit, so as to improve power supply
Reliability.Existing so-called " ring main unit " is exactly that each distribution branch road sets a switch cubicle (outlet switch cabinet), this switch cubicle
Bus simultaneously be exactly ring main a part.That is ring main is connected altogether by the bus of every outgoing line cabinet
With composition.Every outgoing line cabinet is just named " ring main unit ".It is the implication for not seeing " looped network " actually individually to take out a ring main unit
's.The rated current of these ring main units is all little, thus the high-voltage switch gear of ring main unit does not use baroque breaker typically
And take the high voltage load switch simple in construction with high-tension fuse.That is, the high-voltage switch gear in ring main unit is usually
On-load switch.Ring main unit operates normal current with on-load switch, and cuts off short circuit current with fuse, and both, which combines, takes
For breaker.Certainly this can only be confined in certain capacity.Such switch cubicle can also use non-ring network structure completely
In distribution system, then as the extensive use of this switch cubicle, " ring main unit " have just been jumped out the category of looped network distribution and referred to
High-tension switch cabinet using on-load switch as main switch.
Current existing solid loop-net cabinet insulating properties are general, dangerous without overcurrent protection function, use.
Utility model content
In view of this, the utility model purpose is to provide a kind of good insulation preformance, has overcurrent protection function, safe to use
Solid loop-net cabinet.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：

Housing is equipped with, the hull outside is evenly equipped with reinforcement, and the housing is provided at both ends with connecting rod, and the case top is provided with solid
Sealed pole and binding post, the pole outside are provided with terminals and leading-out terminal, and the terminals are connected with bus, described
Leading-out terminal is connected with binding post, and the housing bottom is provided with end cap, is provided with fuse on the end cap, the binding post with
Fuse connects, and the end cap bottom is provided with junction block.
Preferably, the housing is on the inside of connecting rod and cabinet by being connected, connecting rod two end mounting screw respectively with housing and
Cabinet is fixed.
Preferably, the reinforcement is integrally formed with housing, housing and reinforcement are adopted made of plastic, can be molded
Shaping.
Preferably, the junction block is connected with fuse, through hole is provided with the middle part of end cap, junction block electric wire passes through through hole
It is connected with fuse.
Preferably, the end cap is fixedly connected with the casing, end cap both ends are provided with screw and are fixed on housing bottom.
Preferably, the cabinet door is flexibly connected with cabinet, cabinet door can be connected by hinge with cabinet.
The utility model has the technical effect that following aspect：The pole of setting is modularized design, structure
Simply, detachable part is few, and reliability is high, has high insulating bar ability, and surface insulation is become volume and insulated by it, is compared
Air insulation, reduce the influence of environment, substantially increase dielectric strength；The fuse of setting has overcurrent protection function, protects
Hold safe to use.
