Abstract
The utility model discloses an integrated high voltage alternating current vacuum circuit breaker, which is characterized in that two groups of vacuum arc extinguish chambers with same structures are fixed in a same box body to form a double power transfer high voltage switch. The utility model with machinery interlocking design has the advantages of small volume, light weight, low costs and aided function such as manual operation, remote control, intellectualization and super-strong communicating function. Moreover, the utility model avoids the disadvantages of current devices and is an ideal electric network double power switch device.
Description
Technical field
The utility model relates to a kind of integrated high-pressure AC vacuum circuit-breaker, especially is applicable to the high-voltage switch gear that needs the user of uninterrupted power supply duplicate supply to switch in the 10kV distribution line.
Background technology
Along with the development of society, need the user of uninterrupted power supply more and more, adopt 10kV high-pressure side dual power supply to become inexorable trend.Traditional 10kV high-pressure side dual power supply scheme has two kinds, one: adopt the ring main unit design in distribution system; Its two: adopt the active and standby design of vacuum circuit-breaker on the twin columns.
First kind of scheme floor space is big, and the cable consumption is big, causes cost too high.Second kind of scheme though avoided the shortcoming of first kind of design, owing to selected universal vacuum pole-mounted circuit breaker for use, exists the shortcoming that the bulky weight that causes is excessive, difficulty is installed.Other second kind of scheme exists also that reliability is low, conversion speed is slow, is exposed to very easily problem such as deterioration of outdoor switch outlet bus-bar.
Summary of the invention
The utility model purpose is the deficiency at above-mentioned prior art existence, and the design that provides a kind of integral type duplicate supply to switch HVAC vacuum circuit breaker is in the hope of producing low cost, high reliability, the high-voltage switch gear of multi-functional distribution line.
Task of the present utility model is finished by following proposal, promptly mainly by being installed in two groups of vacuum interrupters in the steel box section, being socketed in current transformer, voltage transformer, mechanical interlock, outlet on the lead-in wire terminal and connecting bus-bar, power transmission shaft, the operating mechanism that is installed in the casing outside, controller and be installed in the turnover line that has silicon rubber insulator on the casing etc. and form.It is characterised in that the identical vacuum interrupter of two set constructors is fixed within the same casing, adopts mechanical interlock to constitute a kind of duplicate supply conversion high-voltage switch gear.
Present design has also further designed intelligent controller and data communication module.Controller is in order to electric current, voltage to circuit, information such as the state of switch are analyzed, are handled, and control two groups of vacuum circuit-breakers deciliter, modes such as wireless or optical fiber realize data remote to the data after simultaneously controller will be handled by the communication module employing according to certain form.
According to the integrated high-pressure AC vacuum circuit-breaker of the utility model design compare with existing product have volume little, in light weight, be convenient to install, but and low, powerful, the mechanical interlocked fast communication of high reliability, conversion speed that power supply short circuit can not occur of cost, be aided with manual operation, the remote control design constitutes the multifunctional all switch, is fit to very much the needs duplicate supply and switches the 10kV distribution line.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is an electrical schematic diagram structure chart of the present utility model.
Fig. 2 is a controller electrical schematic diagram block diagram of the present utility model.
Embodiment
A kind of integrated high-pressure AC vacuum circuit-breaker, mainly by being installed in two groups of vacuum interrupters in the steel box section, being socketed in current transformer, voltage transformer, mechanical interlock, outlet on the lead-in wire terminal and connecting bus-bar, power transmission shaft, the operating mechanism that is installed in the casing outside, controller and be installed in the turnover line that has silicon rubber insulator on the casing etc. and form, it is characterized in that the identical vacuum interrupter of two set constructors is fixed within the same casing, adopt mechanical interlock.Constitute a kind of duplicate supply conversion high-voltage switch gear.
The operation principle general introduction:
1. input module: gather voltage and current signal and send main controller module to.
2. power module: gather voltage, power to whole system.
3. actuating module: receive the main controller module signal, carry out circuit breaker and close the branch operation.
4. operational module: receive keyboard signal, controller is instructed transmission.
5. display module: receive controller signals, operation display interface and controller state indication.
6. communication module: finish the processing of controller and aerial signal.
7. master control module: the Based Intelligent Control of whole system is finished.
The course of work:
By keyboard display, carry out its equipment is provided with and checks operating state.The electric current of circuit, voltage, information such as the state of switch are imported the master control module into by input module and are analyzed, handle, and by two groups of vacuum circuit-breakers of actuating module controls deciliter, modes such as wireless or optical fiber realize data remote to the data after simultaneously controller will be handled by the communication module employing according to certain form.
Claims (2)
