Abstract
A kind of KNSJ650-12 armoured removable type alternating, comprise cabinet, bus-bar room, circuit breaker cart room, cable vault, relay control room are established in cabinet inside, described cabinet width is 650mm, bus adopts D-type copper bar and composite insulating material, and built-in switch adopts VSJ-12 type permanent magnetic actuator vacuum circuit breaker.Compared with prior art, bus adopts D type copper bar to the utility model, and the power plant being conducive to surrounding them is uniformly distributed, and strengthen electrical distance, adopt composite insulating material, make the wide 800mm by routine of cabinet be reduced to 650mm, cabinet volume reduces greatly in addition.
Description
Technical field
The utility model relates to field of switch equipment, particularly relates to a kind of KNSJ650-12 armoured removable type alternating.
Background technology
Traditional switchgear, floor space is large, expensive, and very flexible, and reliability is low, changes trouble, can not meet the demand of modern society's switching devices when a certain hardware failure of equipment.
Summary of the invention
The purpose of this utility model provides a kind of volume little to overcome the deficiencies in the prior art, the KNSJ650-12 armoured removable type alternating that overall connecting-disconnecting function is high, insulation property are high, easy to install, safe and reliable to operation.
The purpose of this utility model realizes with following proposal:
A kind of KNSJ650-12 armoured removable type alternating, comprise cabinet, bus-bar room, circuit breaker cart room, cable vault, relay control room are established in cabinet inside, described cabinet width is 650mm, bus adopts D-type copper bar and composite insulating material, and built-in switch adopts VSJ-12 type permanent magnetic actuator vacuum circuit breaker.
Described bus composite insulating material is Raychem heat-shrinkable T bush.
The interlock that described switchgear is provided with and prevents on-load push-and-pull circuit breaker cart, prevent a by mistake point falsely close circuit breaker, close circuit breaker, prevent mistakenly entering into charged compartment, prevent from closing in charged mistiming earthed switch when preventing earthed switch to be in make position.
Compared with prior art, bus adopts D type copper bar to the utility model, and the power plant being conducive to surrounding them is uniformly distributed, and strengthen electrical distance, adopt composite insulating material, make the wide 800mm by routine of cabinet be reduced to 650mm, cabinet volume reduces greatly in addition.The KNSJ650-12 armoured removable type alternating that the utility model provides is mainly used in powered, the place such as power transmission and Large-scale High-Pressure motor start-up of power plant, medium and small generator power transmission, small power station, industrial and mineral enterprises and institutions distribution and power system substation.This switch cubicle can carry out Installation and Debugging and maintenance from front, therefore peace can back-to-back, composition permutatation and by wall install, improve the fail safe of switchgear, flexibility, decrease floor space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A direction view of Fig. 1.
Wherein, A is bus-bar room; B is circuit breaker cart room; C is cable vault; D is relay control room; 1 is cabinet; 2 is dividing plates; 3 is insulators; 4 is bus casings; 5 is bus bar copper rows; 6 is static contact head devices; 7 is contact boxs; 8 is current transformers; 9 is earthed switches; 10 is cables; 11 is earth bus; 12 is lightning arresters; 13 is circuit breaker carts; 14 is isolating switches; 15 is handcart room observation windows; 16 is branch bars.
Embodiment
As shown in Figure 1 and Figure 2, a kind of KNSJ650-12 armoured removable type alternating, comprises cabinet 1, and described cabinet dividing plate 2 is divided into bus-bar room A, circuit breaker cart room B, cable vault C, relay control room D, and cabinet width is 650mm.
Main bus bar selects D type copper bar 5, be conducive to the electric fields uniform distribution of surrounding them, strengthen electrical distance, ensure that the miniaturization of switch cubicle volume, bus casing 4 adopts Raychem heat-shrinkable T bush, further increase bus insulation intensity, branch bar 16 is vertically overlapped in main bus bar.
The interlock that described switchgear is provided with and prevents on-load push-and-pull circuit breaker cart, prevent a by mistake point falsely close circuit breaker, close circuit breaker, prevent mistakenly entering into charged compartment, prevent from closing in charged mistiming earthed switch 9 when preventing earthed switch to be in make position.
Bus-bar room A is provided with insulator 3, static contact head device 6 and contact box 7.
Circuit breaker cart room B is provided with circuit breaker cart 13, can be observed the state of isolating switch 14 and earthed switch 9 by handcart room observation window 15.
Cable vault C is provided with the cable 10, lightning arrester 12, earthed switch 9 and the earth bus 11 that are connected with current transformer 8.
Built-in switch is VSJ-12 type permanent magnetic actuator vacuum circuit breaker or isolating switch, improves switch cubicle power supply reliability.
The content that the utility model is not described in detail is prior art, repeats no more here.This switchgear has built on stilts line, cable goes out to use other function scheme, can become the power distribution equipment of various schematic design making after arrangement, combination.This switch cubicle can carry out Installation and Debugging and maintenance from front, therefore peace can back-to-back, composition permutatation and by wall install, improve the fail safe of switchgear, flexibility, decrease floor space.
