Abstract

The utility model discloses a metal armouring intermediate switchgear cabinet applied to power system substation configuration, the rated work voltage of which is 12 KV, consisting of a maintenance channel, a bus room, an equipment room, a relay room, a breaker handcart room and a cable room. All rooms in the cabinet are separated by metal plates; the shell of each unit has separated grounding and is provided with a pressure release device. Perfect five-prevention function and interlock provide safe protection for operating workers and equipment and the arrangement of the maintenance channel and the observation window prominently shows the convenience and safety of the equipment maintenance.

Description

A kind of metal armouring intermediate switchgear cabinet
It is the metal armouring intermediate switchgear cabinet of 12kv that the utility model relates to a kind of rated operational voltage for the power system transformer substation configuration.
At present, the semienclosed GG-1A type in still imitated five sixties of the former Soviet Union of switch cubicle great majority of the old-fashioned substation operation of China's electric power system, the fixed installation of circuit breaker, this switch cubicle, structure falls behind, and protection level is poor, potential safety hazard is big, if in a single day it break down, the inconvenience maintenance realizes restoring electricity fast and influencing normal operation with replacing, is badly in need of renovating.But this cabinet also has its outstanding advantage, and the primary system space for maintenance is big in the cabinet.And type switch cubicles such as newly-built transformer station configuration JYN, KYN, especially intermediate switchgear cabinet enjoys favor.Intermediate switchgear cabinet is a kind of latest type of withdraw-type armouring cabinet, its advantage is: circuit breaker cart is loaded on the cabinet middle part, the push-and-pull of handcart is carried out in orbit, and the equipped switch cubicle of the circuit breaker cart of same size can be realized exchanging, and this brings great convenience to operation maintenance; The push-and-pull of circuit breaker cart is to realize under the situation of door sealing, gives operating personnel with the sense of security, the degree of protection height.But the problem of upgrading the existence of GG-1A type with this cabinet type is, because two kinds of cabinet type cabinet width and depth difference are very big, original infrastructure such as factory building, cable trough etc. all can not utilize, rebuilding needs to drop into a large amount of funds, thereby it is identical with the GG-1A cabinet and have a KYN type switch cubicle advantage to be badly in need of a kind of its cabinet is wide and cabinet is dark installation dimension, outstanding again embodiment characteristics easy to maintenance, can make full use of existing factory building and underground cable passage again, meet former new cabinet type of having ready conditions fully and be used to the engineering that renovates.
The purpose of this utility model is to provide a kind of switch cubicle that satisfies above-mentioned specification requirement.During transformation, get final product fitting operation after directly old cabinet being removed, not only save fund for technical innovation, shortened the transformation duration again simultaneously.
For achieving the above object; the cabinet type of metal armouring intermediate switchgear cabinet of the present utility model is the metal armouring totally enclosed type; cabinet adopts the strong aluminizing zine plate of antiseptic property; through the CNC lathe dash automatically, cut, bolted after the curved processing; each chamber is separated by metallic plate in the switch cubicle; each cell enclosure all has independently ground connection and is provided with pressure relief device, five anti-functions that switch cubicle is good and interlock provide fail safe for operating personnel and equipment protection.The internal structure of this switch cubicle is made up of access path, bus-bar room, control room, relay bungalow, circuit breaker cart chamber, cable vault.The space that shrouding, fracture dividing plate, observation window, cabinet bottom sealing plate constitute behind side cabinet and circuit breaker cart chamber side plate, access path refractory slab, the cabinet is set to access path.Observation window and circuit breaker cart septum of ventricles of heart plate, the mutually orthogonal connection of fracture dividing plate make bus-bar room constitute closed cell.
This observation window can be dismantled and be manufactured by the clear polycarbonate plate.
Below in conjunction with accompanying drawing embodiment of the present utility model is done further detailed description.
Fig. 1 is the cabinet front layout plan of a kind of metal armouring intermediate switchgear cabinet of the utility model embodiment.
Fig. 2 is the cutaway view of Fig. 1.
Fig. 3 is the partial sectional view of a kind of metal armouring intermediate switchgear cabinet of the utility model embodiment.
Cabinet 1 front is provided with relay bungalow 2 as seen from Figure 1, access path 3, control room 4, circuit breaker cart chamber 5,6 five functional units in cable vault.
Bus-bar room Unit 7 are positioned at cabinet 1 right back top as seen from Figure 2, and circuit breaker cart septum of ventricles of heart plate 8 is connected with fracture dividing plate 9 quadratures, it can also be seen that the control room's door 10, circuit breaker cart chamber door 11, the cable vault's door 12 that are positioned at cabinet 1 positive right side of face.
Bus-bar room pressure release valve 13 is arranged at the top of cabinet 1 as seen from Figure 3, circuit breaker cart chamber pressure release valve 14, lintel head 17, cabinet 1 left upper portion relay bungalow door 18, bottom, left side access path door 21.Also the space that shrouding 16, fracture dividing plate 9, observation window 15, cabinet bottom sealing plate 23 constitute behind side cabinet 20 and circuit breaker cart chamber side plate 22, access path refractory slab 19, the cabinet as can be seen is set to access path 3.It can also be seen that observation window 15 and circuit breaker cart septum of ventricles of heart plate 8,9 mutually orthogonal connections of fracture dividing plate make bus-bar room 7 constitute closed cell.
This observation window 15 can be dismantled and be manufactured by the clear polycarbonate plate.
The utility model embodiment enables the operation sequence of access path 3: make the circuit breaker cart separating brake earlier and be in the experiment position, can open access path door 21, after the maintainer leans to one side to enter access path 3, can safeguard the following primary line of fracture under circuit breaker system, can also watch from a height or a distance the above primary line of fracture system by observation window 15, when the maintainer observes when unusual, can after confirming power failure, pull down observation window 15 and enter bus-bar room 7 operations, install observation window 15 after finishing again, shut access path door 21, recover normal operation again.
After adopting such structure, the utility model namely has the advantage of KYN type series switch cabinet, The more outstanding reliable wall of cabinet that embodied is installed, the convenience that can before cabinet, carry out again the plant maintenance maintenance with Security.

Claims (2)

1, a kind of metal armouring intermediate switchgear cabinet, be made up of access path, bus-bar room, control room, relay bungalow, circuit breaker cart chamber, cable vault, it is characterized in that: the space that shrouding (16), fracture dividing plate (9), observation window (15), cabinet bottom sealing plate (23) constitute behind side cabinet (20) and circuit breaker cart chamber side plate (22), access path refractory slab (19), the cabinet is set to access path (3); Observation window (15) and circuit breaker cart septum of ventricles of heart plate (8), the mutually orthogonal connection of fracture dividing plate (9) make bus-bar room (7) constitute closed cell;
