Abstract
The utility model relates to a circuit breaker controlled intensively, which comprises an operating mechanism of the circuit breaker, a secondary control part of the operating mechanism of the circuit breaker, an underframe and a stanchion porcelain insulator. The utility model is characterized in that a conversion switch, a switching on-off coil and a motor controlling part on operating mechanism of the circuit breaker are fixed on an operating mechanism of which the control joint is extracted through a cable socket connector. The stanchion porcelain insulator is fixed on the upper end of the underframe, and the operating mechanism is fixed in the underframe. A secondary control part of an operating mechanism of a three-phase circuit breaker is fixed in a sink controlled cabinet. A shell is covered outside the operating mechanism of the circuit breaker. The secondary control part of an operating mechanism of a three-phase circuit breaker is electrically connected with the operating mechanism through a cable and the cable socket connector. The central circuit breaker controlled intensively has the advantages of convenient maintenance, good reliability and high installation efficiency.
Description
Technical field
The utility model relates to a kind of circuit breaker, especially for the central controlled circuit breaker of the high pressure sulfur hexafluoride of electric power system control and protection.
Background technology
The porcelain knob that 252kV in the market is above or the structure of potting breaker generally are three-phases, and every be furnished with a mechanism case mutually, and the operating mechanism of each phase and the equal mounting arrangements of control system components and parts are in mechanism case.During the product operation, three controls that link connect by threephase cable and to carry out, the disadvantage of this structure is: operating mechanism and control section coexist in the mechanism case, because the operating mechanism monnolithic case is cylindrical, and the profile of control section is flat-square shaped, make that mechanism's casing overall structure is a cuboid, volume is big, and space availability ratio is not high; When secondary connection and control element overhaul or change during on-the-spot the installation, need the opening mechanism chamber door, meetings such as outside adverse circumstances such as dirt sand, moisture exert an influence to operating mechanism; And operating mechanism is in when operation, and the vibration in its operating process also can exert an influence to secondary component; In addition, circuit breaker secondary connection workload when using on-the-spot the installation is big.
Summary of the invention
The purpose of this utility model provides a kind of central controlled circuit breaker, and it overhauls convenient, good reliability, installation effectiveness height.
The technical solution of the utility model is: design a kind of central controlled circuit breaker, it comprises breaker operation mechanism, breaker operation mechanism secondary control section, underframe, support insulator, it is characterized in that: change over switch, divide-shut brake coil, Electric Machine Control partly are fixed on the operating mechanism on the breaker operation mechanism, and its control contact is drawn by cable connector; Support insulator is fixed in the underframe upper end, operating mechanism is fixed on underframe inside, three-phase breaker operating mechanism secondary control section is fixed in the convergence control cabinet, the breaker operation mechanism outside is covered with shell, and three-phase breaker operating mechanism secondary control section is electrically connected with operating mechanism by cable and cable connector.
Characteristics of the present utility model are: the present invention separates gas circuit and circuit; operating mechanism is fixed in the underframe; operating mechanism is covered with a cylinder blanket; the shell sizes of this operating mechanism outer mask is a bit larger tham breaker operation mechanism maximum outside diameter size; littler and take up space for a short time than known shell sizes, keep dustproof, rainproof and protective effect simultaneously.The secondary control section of three-phase breaker operating mechanism is contained in centralized control in the convergence control cabinet, on the operating mechanism control point draw and this control point is introduced to convergence control cabinet and is all used cable and plug connector to connect, on-the-spot easy for installation, workload is little, and installation quality also will be along with raising.And because gas circuit and circuit are separately, concentrate at circuit part, to control system maintenance and user when the control element of rapid wear is changed, only need open control cubicle and need not the protecting crust of opening mechanism, avoided influence such as outside adverse circumstances such as dirt sand, moisture etc. to mechanism's parts, simultaneously also avoided mechanism when actuating, vibration has improved reliability to the influence of secondary component; In addition, because three-phase control concentrates in the convergence control cabinet, the wiring between each element is comparatively convenient, and the consumption of connecting terminal block greatly reduces, and has saved material and space.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is further specified.
Accompanying drawing 1 is the example structure schematic diagram.
Among the figure: 1, support insulator; 2, underframe; 3, jockey; 4, breaker operation mechanism; 5, mechanism's outlet plug connector; 6, stube cable; 7, on-the-spot line trench; 8, convergence control cabinet inlet wire plug connector; 9, convergence control cabinet.
Embodiment
In Fig. 1, support insulator 1 is fixed in underframe 2 upper ends and connects by screw, and breaker operation mechanism 4 is fixed in the underframe 2, and jockey 3 couples together support insulator 1 and underframe 2 with operating mechanism 4; Control contacts such as change over switch, divide-shut brake coil, motor are connected on mechanism's outlet plug connector 5 by insulated wire on the operating mechanism 4, and by numbering corresponding one by one (each contact of plug connector plug and socket all has corresponding numbering), after each contact carefully connected the wire, the socket of mechanism's outlet plug connector 5 was fixed on the operating mechanism shell; Each contact of plug of mechanism's outlet plug connector 5 is connected with each contact of plug of convergence control cabinet inlet wire plug connector 8 by stube cable 6, and when installed at the circuit breaker scene, stube cable 6 placed on-the-spot line trench 7; Be fixed on the convergence control cabinet 9 on convergence control cabinet inlet wire plug connector 8 sockets, each contact of this socket and plug correspondence is connected on the terminal board in the convergence control cabinet 9 by insulated wire and is connected with each secondary controlling parts then.The circuit breaker secondary control system all carries out in convergence control cabinet, thereby finishes the concentrated secondary control to circuit breaker.In order to transport and packaged convenience, mechanism's outlet plug connector plug at stube cable 6 and two ends thereof and convergence control cabinet inlet wire plug connector plug are not connected with its socket when dispatching from the factory, and only need during on-the-spot the installation itself and respective socket plugged to get final product.
