Abstract
The utility model discloses an arrangement structure of mutual -inductor in cubical switchboard establishes the back crosspiece in the cubical switchboard, a looks mutual -inductor and C looks mutual -inductor are installed on the back crosspiece, B looks mutual -inductor is installed on the internal wall of the back opposed cabinet of crosspiece, B looks mutual -inductor is installed in the earthing switch top. The utility model discloses an optimization of component is arranged in the cabinet, has expanded typical scheme application range. Through meticulous range, reasonable layout, make the structure compacter, optimized the design, reduce the construction investment, reduced the soil volume of occuping, brought considerable economic benefits.
Description
Technical field
The utility model is related to switch cubicle field.
Background technology
At present country's KYN28A-12 standard small electric currents (≤1250A) switch cabinet body is 800X1500X2300 (wide X depths
X is high), when rated current is more than 1250A, cabinet size need to just be increased to 1000mm width (being apart now 275mm), be limited to cabinet
Body structure design and breaker structure are designed, and standard 800mm width cabinet is alternate at a distance of being 210mm, causes matching used with cabinet
Current transformer profile width dimensions are required no more than 210mm (installing 3 transformers), and existing many state's net Project Technicals
High (up to 4 sets of windings), it is desirable to which transformer Secondary Winding many (and the also band taps having), output capacity is big, dynamic current, heat
Stabling current has high demands, but electric current no-load voltage ratio is simultaneously less, is to ensure technical parameter, can only use the nonstandard mutual inductance of big appearance and size
Device, when project needs to use transformer of the width dimensions more than 210mm, routine can only widen cabinet and arrive using scheme
1000mm, and have breaker (≤1250A) when without with 1000mm width cabinets breaker (now breaker be nonstandard, some factories
Family does not produce, such as the VD4 breaker small currents of ABB AB when without at a distance of 275 products, with 1000mm width breaker standard phases
Away from for 275mm), cause to make using nonstandard cabinet, so as to cabinet outward appearance unsightly, bus connection is difficult in cabinet, causes
The waste of the main busbar of level and the waste of cabinet steel in cabinet, also reduce in-site installation space, waste switchgear house and use space.
Utility model content
Technical problem to be solved in the utility model is to realize a kind of internal component connection and reasonable arrangement, convenient to install and not
The switch cubicle of mutual interference can be produced.
To achieve these goals, the technical solution adopted in the utility model is：The arrangement knot of transformer in switch cubicle
Structure, sets back cross rail in switch cubicle, A phases transformer and C phases transformer are arranged on the back cross rail, after B phase transformers are arranged on
On the cabinet inwall on crosspiece opposite, the B phases transformer is arranged on earthed switch top.
The installation site of the A phases transformer and C phase transformers is slightly above the installation site of B phase transformers.
The a width of 800mm of the switch cubicle, the transformer width is 224mm.
The switch cubicle front upper part is control room, and upper back is bus-bar room, and front middle part is relay bungalow, subjacent cable outlet
Room part, between the relay bungalow and bus-bar room pressure release passage is provided with.
Cable outlet room bottom is provided with cable aperture.
The preferred arrangement that the utility model passes through cabinet interior element, extends typical scenario use range.By arrangement meticulously,
Rational deployment, make structure compacter, optimize design, reduce construction investment, reduce land seizure amount, bringing can
The economic benefit of sight.
Description of the drawings
The mark in the content and figure of every width accompanying drawing expression in the utility model specification is briefly described below：
Fig. 1 is inside switch cabinet layout partial schematic diagram；
Mark in above-mentioned figure is：1st, switch cubicle；2nd, back cross rail；3rd, transformer；4th, earthed switch.
Specific embodiment
Technical problem to be solved in the utility model is, by optimizing cabinet interior element arrangement, to reach cabinet profile chi
It is very little to be adjusted to 800X1500X2300 (wide X depths X is high), and the width of transformer 3 is installed up to 224mm, without the need for adopting width 1000mm cabinets
Body, you can achieve the goal.
3 transformers, 3,3 installation sites of transformer 3 are provided with switch cubicle 1 install from cabinet back cross rail 2 and be changed to A, C phases
Cabinet back cross rail 2 is still arranged on, the cabinet middle part installation site of earthed switch 4 is moved down from normal place, B phases transformer 3 is arranged on
The upper end of earthed switch 4, as shown in Figure 1.
To former cabinet body structure, " front upper part is control room to the utility model in high-voltage board, and upper back is bus-bar room, relay
Pressure release passage is provided between room and bus-bar room, breaker is installed at cabinet middle part, and bottom is cable outlet room part.Cable outlet room bottom
Portion is provided with cable aperture, to facilitate the access of power cable " any variation is not done, facilitate the standard of cupboard making and cabinet part
Change, remain the type cabinet and install easy, the characteristics of easy to use.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model is implemented not by above-mentioned
The restriction of mode, if the improvement of the various unsubstantialities that method of the present invention design and technical scheme are carried out is employed, or not
It is improved by the present invention design and technical scheme directly apply to other occasions, protection domain of the present utility model it
It is interior.
