Abstract
A high-voltage switch cabinet with the positions of a current transformer and a grounding switch changed relates to the technical field of switch cabinets and is used as a power distribution device for receiving or distributing power. The upper part inside the switch cabinet comprises a bus chamber, a circuit breaker chamber positioned on one side of the bus chamber and a cable chamber positioned below the bus chamber, wherein the bus chamber is internally equipped with bus-bars, inlet and outlet cables are led out from the inside of the cable chamber, a current transformer is installed below the bus chamber, the cable chamber is internally provided with a lower partition plate, an operating shaft is installed below the circuit breaker chamber, a part of the operating shaft is positioned in the cable chamber, the part, positioning in the cable chamber, of the operating shaft is connected with a grounding switch, and the grounding switch is transversely and vertically installed on the lower partition plate. According to the high-voltage switch cabinet, electrical gaps among the grounding switch, the current transformer and the outlet cable are increased, the security of the electrical gaps is higher, and the space layout is more reasonable after the installation positions of the elements in the cable chamber are changed.
Description
Technical field
The utility model relates to switch cubicle technical field, is specifically related to a kind of high-tension switch cabinet that changes earthed switch position and current transformer position.
Background technology
Electric clearance in high-tension switch cabinet can directly have influence on the product quality of high-tension apparatus, the product quality of high-tension switch cabinet, and except components and parts are selected quality, another key factor is exactly electric clearance.There is special standard in electric clearance country, being greater than national standard is a high standard, the in the situation that of shell size constancy, increase electric clearance, all the time be the direction that switch cubicle manufacturer makes great efforts, electric clearance is large is conducive to the stability of product quality, and equipment will facilitate in postrun maintenance and maintenance.High-tension distribution equipment is that high voltage source is subject to carry out from new distribution after electricity, and its feed quality will directly have influence on the power quality of hypomere equipment, and involvement aspect is very wide.Be an effect of leading whole body.So the quality of high-tension switch cabinet itself is considerable, the quality that improves high-tension switch cabinet is the endless striving direction of high-tension switch cabinet manufacturer.On market, each company's product of inside switch cabinet layout is all different now, and instrument transformer position and earthing unification are contained in after cabinet.The installation of this earthed switch position and current transformer position is all inconvenient to production and field operation and later maintenance, and internal electric gap is less, is unfavorable for components and parts heat radiation.
Utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, a kind of high-tension switch cabinet that changes earthed switch position and current transformer position reasonable in design.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of high-tension switch cabinet that changes earthed switch position and current transformer position, it is the power distribution equipment as acceptance or power distribution, this switch cubicle internal upper part is provided with bus-bar room, be positioned at the breaker chamber of bus-bar room one side and be positioned at the cable vault of bus-bar room below, in described bus-bar room, busbar is installed, in described cable vault, lead to line cable, current transformer is installed below described bus-bar room, in described cable vault, be provided with lower clapboard, described breaker chamber below is provided with operating axis, a described operating axis part is positioned at cable vault, a part that is arranged in cable vault on described operating axis is connected with earthing, laterally vertical being arranged on lower clapboard of described earthing.
Described current transformer is lifted on bus-bar room below, has liberated the space of cable vault, has changed equipment electric clearance in cabinet, has also directly changed the installation site of first and second element in cabinet simultaneously.
Described bus-bar room and breaker chamber separate by upper spacer.
A part that is arranged in cable vault on described operating axis is arranged with insulating sleeve.
The beneficial effects of the utility model are: by adopting technique scheme, increased the electric clearance of earthed switch and current transformer and outlet cable, the fail safe of electric clearance is after more Gao Liao，Ba cable vault component installation location changes, more rationalization of space, when producing, being convenient to bus installs, secondary connection facilitates the examination and test of products simultaneously, is convenient to site operation personnel line cable and installs while coming into operation in the later stage, the maintaining of equipment, replacement of element.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of high-tension switch cabinet that changes earthed switch position and current transformer position, it is the power distribution equipment as acceptance or power distribution, this switch cubicle internal upper part is provided with bus-bar room 1, be positioned at the breaker chamber 2 of bus-bar room 1 one sides and be positioned at the cable vault 3 of bus-bar room 1 below, busbar 4 is installed in bus-bar room 1, in cable vault 3, lead to line cable 5, current transformer 6 is installed below bus-bar room 1, in cable vault 3, be provided with lower clapboard 7, breaker chamber 2 belows are provided with operating axis 8, operating axis 8 parts are positioned at cable vault 3, a part that is arranged in cable vault 3 on operating axis 8 is connected with earthing 9, horizontal vertical being arranged on lower clapboard 7 of earthing 9.Current transformer 6 is lifted on bus-bar room 1 below, has liberated the space of cable vault 3, has changed equipment electric clearance in cabinet, has also directly changed the installation site of first and second element in cabinet simultaneously.Bus-bar room 1 and circuit breaker Room 2 separate by upper spacer 10, and a part that is arranged in cable vault 3 on operating axis 8 is arranged with insulating sleeve.
The utility model changes position by earthed switch and is arranged on dorsad breaker chamber below, current transformer is arranged on bus-bar room bottom, improve greatly in space during the better like this space that utilizes cable vault after cabinet, and it is large that electric clearance also just becomes, and is conducive to the stability of product quality, also convenient production installed simultaneously, repair and maintenance, space, later stage element replacement Deng， cable vault gets a promotion, the installation of giving subsequent branches bus, secondary cabling saved for 15% time.Can save bus and make material 5% simultaneously.
Technical solutions of the utility model are applicable to the high-tension switch cabinet with KYN28-12 high-tension switch cabinet structure similar.
Technical solutions of the utility model change earthed switch position and current transformer position by KYN28-12 high-tension switch cabinet, have changed cable vault's space layout, make the strain of electric clearance phase large, the stable operation of favourable element.Be beneficial to maintaining and the maintenance of equipment.
