Abstract
The invention discloses a 10kV ring main unit occupying quite small space. The ring main unit comprises an isolator chamber, a lightning arrester, a fixed beam, a voltage transformer, an inlet wire cable, an inlet wire cable rack, a current transformer, a circuit breaker chamber, a vacuum circuit breaker and a ring main unit, and is characterized in that the isolator chamber is arranged on the upper part of the ring main unit; the circuit breaker chamber is arranged on the lower part; the lightning arrester is connected with the fixed beam; the voltage transformer is connected with the fixed beam; the current transformer is fixed on the inlet wire cable rack; and the vacuum circuit breaker is installed on the upper part of the circuit breaker chamber. In this way, by properly arranging the voltage transformer, the current transformer and the lightning arrester in the ring main unit, the 10kV ring main unit is enabled to occupy quite small space; the installation efficiency is quite high; and the later maintenance is quite convenient and easy.
Description
Technical field
The invention belongs to distribution box cabinet field, which is related to a kind of 10kV ring main units for taking up room less.
Background technology
Ring main unit is one group of transmission ＆ distribution electrical equipment（High-tension switch gear）It is mounted in metal or non-metallic insulation cabinet or makes the electrical equipment of assembled compartment ring network power supplying units, its core adopts on-load switch and fuse, has the advantages that simple structure, small volume, price are low, can improve power supply parameter and performance and power supply safety.It is widely used in the power distribution station and box-type substation of the load centers such as Urban Residential District, skyscraper, large public building, factory and enterprise.
With the development and the raising of living standards of the people of society, the extensive application of electric power, 10kV ring main units play an important role in field of power distribution, existing 10kV ring main units have two kinds of mounting means, a kind of is point cabinet placement of current transformer and voltage transformer and vacuum circuit breaker, one kind is that the layering of current transformer, voltage transformer and vacuum circuit breaker is placed in same ring main unit, it is very big that both mounting means all cause 10kV ring main units to take up room, and installation process is complicated, is unfavorable for the maintenance in later stage.
The content of the invention
It is an object of the invention to provide a kind of 10kV ring main units for taking up room less so that 10kV ring main units take up room less, and faster, and later maintenance is more convenient for installation effectiveness.
The technical scheme is that：A kind of 10kV ring main units for taking up room less, including ring network cabinet body, isolator room, spark gap, fixed beam, fixed beam, voltage transformer, inlet wire cable, inlet wire cable trough, current transformer, breaker chamber, vacuum circuit breaker, the ring network cabinet body top is isolator room, bottom is breaker chamber, the spark gap, fixed beam, voltage transformer, inlet wire cable, inlet wire cable trough, current transformer, vacuum circuit breaker is arranged on breaker chamber, the spark gap is connected with fixed beam, the voltage transformer is connected with fixed beam, the current transformer is fixed on inlet wire cable trough, the vacuum circuit breaker is arranged on the top of interruption chambe's device.
The invention has the beneficial effects as follows：The present invention provides a kind of 10kV ring main units for taking up room less, by voltage transformer, current transformer, the rational deployment of spark gap is placed in a ring main unit, so that 10kV ring main units take up room less, faster, and later maintenance is more convenient for installation effectiveness.
Description of the drawings
Fig. 1 is a kind of 10kV ring main unit schematic diagrams for taking up room less.
In figure：Isolator room 1, spark gap 2, fixed beam 3, voltage transformer 4, inlet wire cable 5, inlet wire cable trough 6, current transformer 7, breaker chamber 8, vacuum circuit breaker 9, ring network cabinet body 10.
Specific embodiment
In order that the purpose of the present invention, technical scheme and beneficial effect become more apparent, with reference to embodiments, the present invention will be described in further detail.Should be understood to that specific embodiment described herein, only to explain the present invention, is not limited to protection scope of the present invention.
As shown in Figure 1：The invention provides a kind of 10kV ring main units for taking up room less, including isolator room 1, spark gap 2, fixed beam 3, voltage transformer 4, inlet wire cable 5, inlet wire cable trough 6, current transformer 7, breaker chamber 8, vacuum circuit breaker 9, ring main unit 10；10 top of the ring main unit is isolator room 1, bottom is breaker chamber 8, and the spark gap 2 is connected with fixed beam 3, and the voltage transformer 4 is connected with fixed beam 3, the current transformer 7 is fixed on inlet wire cable trough 6, and the vacuum circuit breaker 9 is arranged on the top of interruption chambe's device 8.
The present invention when in use, by voltage transformer, current transformer, the rational deployment of spark gap are placed in a ring main unit so that 10kV ring main units take up room less；Cabinet need not be divided to install as current transformer and voltage transformer and vacuum circuit breaker are arranged in a ring main unit so that installation effectiveness is faster；During later maintenance, installed due to each part and compare concentration, investigation problem and maintenance of equipment are more convenient.
One embodiment to inventing has been described in detail above, but institute's content is only that present pre-ferred embodiments are not to be regarded as limiting the scope of the present invention.All impartial changes done according to the present patent application scope and improvement etc., all should still belong to the patent covering scope of the present invention.
