Description

A kind of indoor closed ring main unit
Technical field
The utility model belongs to circuit and installs machinery equipment field, and in particular to a kind of indoor closed ring main unit.
Background technology
Looped network refers to that ring distribution system, i.e. supply main form the annular of a closure, and power supply is dry to this annular Line is powered, and passes through the outside distribution of high-voltage switch gear all the way again from main line.Such benefit is that each distribution branch road was both Can be from its left 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 it is just from the right side Side main line continues to be powered, and when right side main line is out of order, it just continues to be powered from left side main line, so, Although general supply is single service, obtain being similar to the material benefit supplied power with double circuit for each distribution branch road, so that Improve the reliability of power supply.So-called " ring main unit " is exactly that each distribution branch road sets a switch cubicle (outlet switch cabinet), this The bus of switch cubicle is exactly a part for ring main simultaneously.That is, ring main is by the bus connection of every outgoing line cabinet Get up what is collectively constituted.Every outgoing line cabinet is just named " ring main unit ".It is not see " looped network " actually individually to take out a ring main unit Implication.The ring main unit that current China uses is higher, it is necessary to which dedusting, ventilation, air dehumidifying etc. are supporting to placing environmental requirement Equipment, involves great expense.
Utility model content
The purpose of this utility model, which is that, provides a kind of indoor closed ring main unit in order to solve the above problems.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of indoor closed ring main unit, including ring network cabinet body, on-load switch, side access panel and distribution transformer, It is provided with above the ring network cabinet body above vacuum orifice, the vacuum orifice and main switch is installed, above the main switch It is provided with above the on-load switch, the on-load switch and is provided with main operation panel, is provided with above the main operation panel It is provided with above breaker, the breaker above transformer controller, the transformer controller and is connected with the side sight Examine to be provided with below plate, the side access panel below fuse, the fuse and sound-deadening and noise-reducing device is installed, the noise reduction drop Make an uproar and emergency stop button is communicated with below device, the distribution transformer, the distribution are installed below the emergency stop button Internal barrier is installed above transformer.
Further, the ring network cabinet body is connected with the vacuum orifice, and the main switch connects with the on-load switch Connect.
Further, the main operation panel is connected with the breaker, and the transformer controller is seen with the side Examine plate connection.
Further, the fuse is connected with the sound-deadening and noise-reducing device, and the emergency stop button becomes with the distribution Depressor is connected.
Further, the internal barrier is connected with the side access panel, the main operation panel and the noise reduction Denoiser is connected.
Beneficial effect is:Inside can be vacuumized, and ring main unit internal component effectively can be protected, drop Low requirement of the ring main unit to environment, reduces the investment cost of ring main unit computer room.
