Abstract
The requirements of common distribution electric lines in rated voltage 12kV, such as a high-voltage circuit breaker with a current mutual inductor, a fuse and a voltage mutual inductor can be satisfied through two high-voltage switch cabinets at pressure, while the utility model can satisfy the requirements only by one high-voltage switch cabinet, has the beneficial effects of cost reduction, efficiency improvement, simpleness, practicability, safety and reliability, and reduces the area of the capital construction of a power distribution house. The utility model is provided with an upper handcart and a lower handcart in a single high-voltage switch cabinet casing on the basis of not changing the dimension of an existing high-voltage switch cabinet, namely the upper handcart is arranged in the middle front portion of the high-voltage switch cabinet casing for installing a high-voltage circuit breaker, and the lower handcart is arranged in the lower front portion of the high-voltage switch cabinet casing for installing a high-voltage fuse and a high-voltage voltage mutual inductor, a high-voltage current mutual inductor is arranged on the upper space at the back of a cable chamber in the high-voltage switch cabinet casing, and a high-voltage feed cable is connected in the middle space of the cable chamber.
Description
Technical field
The utility model is that a kind of rated voltage is the high-tension switch cabinet of the built-in handcart structure of 12kV.Its inner constructional form feature is that two handcarts of levels are set in the separate unit high-tension switch cabinet, can realize the situation that present two high-tension switch cabinets of needs just can meet the demands with the separate unit high-tension switch cabinet when being used for some high-voltage electrical apparatus circuit schemes commonly used.
Background technology
The high-voltage electrical apparatus circuit has multiple standard distributed circuit scheme commonly used.The high-tension switch cabinet of the built-in handcart structure of rated voltage 12kV all is the structural form that cabinet is provided with a handcart at present, it for example need adopt two cabinet sub-portfolios just can meet the demands during the scheme of primary cut-out distribution current transformer, fuse, voltage transformer when realizing some electric wiring schemes commonly used.Such structural form has increased the investment cost of controller switching equipment, and will take more power distribution room capital construction area.
The utility model content
Some distribution electric wiring schemes commonly used for rated voltage 12kV, the utility model needing at present to realize two situations that high-tension switch cabinet just can meet the demands with the separate unit high-tension switch cabinet, its technical scheme that adopts is: under the prerequisite that does not change existing high-tension switch cabinet overall dimension, design is placed in two handcarts in the separate unit cupboard, form the structural form of two-layer handcart up and down, middle front part position design in switch cubicle settles the upper strata handcart so that primary cut-out to be installed, and the front design settles lower floor's handcart so that high-tension fuse and high voltage potential transformer to be installed under switch cubicle.Simultaneously, in switch cubicle for install be connected high-tension current inductor, the high-voltage feedback power cable leaves enough spaces, so that settle high-tension current inductor in the upper back of switch cubicle inner cable chamber spatial design, the central space design in the cable vault connects the high-voltage feedback power cable.
The utility model satisfies the usefulness that present needs two cabinets could be realized the distribution electric wiring scheme that some are used always with the separate unit high-tension switch cabinet, has the beneficial effect of cost efficiency, simple and practical, safe and reliable and minimizing power distribution room capital construction area.
