In the composite and combined electrical device provided by the utility model, being connected via the conductors positioned in the SF6 gas, so that the electrical elements are free from the affection of the use environment, and can be used in high-altitude and highly dirty environment; the bus-bar is opened, so that the gas usage quantity is greatly reduced, the cost and the environmental pollution of the SF6 gas are lowered, the maintenance is convenient, and the time for power off is greatly shortened; a porcelain busing adopts a composite insulator, so that the weight is light, and pollution resistance and flash resistance are strong; a traditional product and an electronic product can be mounted, so that the intelligent degree of the product is higher; and three phases are positioned in different air chambers, so that the interference possibility is greatly reduced.
Description
Technical field
The utility model relates to a kind of compound combined electrical equipment, is specifically related to a kind of complete semi-enclosed high voltage switchgear system of control, measurement, protection, isolation and the switching that is used for power plant, power station, factory's controller switching equipment and railway electrification equipment.
Background technology
Combined electrical apparatus is the electrical equipment with two or more, form a whole by the wiring requirement, and each electrical equipment still keeps the device of former performance, and its compact conformation, outline overall and installing dimensions is little, and is easy to use, and the performance of each electrical equipment cooperation better.Can be divided into low pressure combined electrical apparatus and high pressure combined electrical apparatus by voltage height, the high pressure combined electrical apparatus is divided into two kinds of open type and totally enclosed types by insulation system.The former is based on isolating switch or circuit breaker, with current transformer, voltage transformer, the first-class element of cable with it common combination form, all elements are traditional product, and are intelligent, degree of miniaturization is not high.The latter is that the electrification in high voltage position with each element is sealed in the grounded metal enclosure, fill in the shell with the good gas of insulation property, oil or solid dielectric insulation, each element, generally comprise circuit breaker, isolating switch, earthed switch, voltage transformer, current transformer, bus, lightning arrester, cable termination etc. by the wiring requirement, connect successively and form a whole.This infrastructure cost is higher.
The utility model content
In order to adapt to the requirement of present intellectuality, miniaturization, the utility model has designed a kind of high-voltage electrical equipment between open combined electri cappliance and fully closed combined electric unit, intelligent, modular.This product reliability is higher, and intelligent degree is better.
Technical solution of the present utility model:
A kind of compound combined electrical equipment comprises circuit breaker, current transformer, three-station, instrument transformer, high speed grounding switch, main bus bar, outlet sleeve pipe, and each electric elements is by being in the SF in the closed container
6Gas and epoxy casting insulator carry out electric insulation, carry out electrical communication by interconnective conductor, and the turnover kind of thread elements adopts sleeve pipe or cable turnover line.
Described main bus bar is for opening wide the pipe bus of arranging.
Described insulator is a composite insulator.
Described circuit breaker is a three-phase split-phase type potting breaker.
Described instrument transformer is an electronic mutual inductor.
Described instrument transformer is an electromagnetic transformer.
The beneficial effects of the utility model:
Because each electric elements is by being in SF
6Conductor in the gas connects, and therefore is not subjected to the influence of environment for use, can be used in high height above sea level, the high filthy environment.Bus is an open type, so gas consumption significantly reduces, and has reduced cost and SF
6The environmental pollution of gas, and easy access, interruption duration shortens greatly; Insulator adopts composite insulator, and in light weight, the anti-sudden strain of a muscle ability of anti-soil is strong; Both the traditional type product can be installed, and also the electronic type product can be installed, the intelligent product degree is higher; Three-phase is arranged in different air chambers, and the possibility that interferes with each other reduces greatly.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
As shown in the figure, this novel combined combined electrical apparatus comprises circuit breaker 1, current transformer 6, three-station 4, three-station mechanism 5, high speed grounding switch 2, outlet sleeve pipe 3, secondary control cubicle 8.The circuit breaker 1 of three-phase phase-splitting and mechanism adopt the mechanical linkage mode to carry out transmission, and major function is to realize cut-offfing, closing and close and transfer load of normal current or abnormal current.Breaker mechanism is power set of realizing the operation of circuit breaker; Current transformer 6 can be selected electronic current mutual inductor or electromagnetic-type electronic instrument transformer as required, is installed in circuit breaker 1 turnover line two ends, and the metering and the guard signal of electric current can be provided.Three-station 4 is installed on the top of current transformer 6, and major function is the isolation of electrified body when realizing maintenance and the ground connection of electrified body not, guarantees the safety of overhauling.Three-station mechanism 5 is operation power plants of realizing three-station; Fast earthed switch mechanism is the power set that three stations are realized quick ground connection.Compound combined electrical equipment can install elements such as lightning arrester, voltage transformer as required additional, also can install the intelligent element of external additional and make it possess the feature of "smart" products.Secondary control cubicle 8 is control device of compound electric apparatus, can realize between each electric elements of compound electric apparatus, each short range between compound electric apparatus or Long-distance Control, contact function at interval.Also can add intelligent control unit makes it possess the feature of "smart" products.Satisfy the various main wiring mode needs of user.
To sum up the utility model accomplishes the end in view.
