Description

A kind of direct-current breaker topology

Technical field

The present invention relates to a kind of circuit breaker, be specifically related to a kind of DC circuit breaker.

Background technology

Fast DC Circuit Breaker is one of key equipment ensureing direct current transmission and distribution system and direct current network system stability safe and reliable operation.Be that the electric current of direct current system does not exist natural zero-crossing point with AC system difference, the natural zero-crossing point of electric current therefore cannot be utilized in direct current system as AC system to turn off, therefore the problem of cut-offfing of direct current is a problem being worth research always.

Current breaking direct current has two kinds of modes usually, and the first is pure power electronics circuit breaker, as the patent CN102870181A of ABB application, utilizes and high-powerly turns off power electronic device, direct disjunction direct current.Utilize the solid circuit breaker that this principle manufactures, although can meet the requirement of multiterminal flexible direct current system in time, the loss when normally is excessive, and economy is poor.

The second is mixing Circuit breaker technology, namely on the basis of traditional interchange mechanical chopper, by increasing auxiliary Power Electronic Circuit, dropping into current-limiting resistance to reduce short circuit current or superimposed oscillation electric current on the direct current cut-offfing arc gap, utilizing during current over-zero and cut-off circuit.Utilize the hybrid circuit breaker that this principle manufactures, it has particular/special requirement to mechanical switch, the more difficult requirement meeting DC transmission system on break-time.

The one mixing circuit breaker that Siemens patent WO2013/093066A1 proposes, primary path is connected mechanical switch and power electronics controls device entirely, another bypass is made up of electric capacity, when fault current being detected, on primary path, power electronics controls device disconnection entirely, mechanical switch also starts to cut-off, fault current charges to shunt capacitance, the shunt capacitance of this circuit can not value too small, otherwise mechanical switch is opened not yet completely, if shunt capacitance too fast meeting of voltage rise under fault current charging exceedes mechanical switch and power electronic device bears electric pressure.But capacitance value large time, the speed of cut-offfing will be affected.

The one that the patent WO2011141054A1 of ABB AB proposes mixes circuit breaker, primary path is connected mechanical switch and power electronics controls device entirely, another bypass is composed in parallel by lightning arrester and crimping IGBT, when fault current being detected, the whole conducting of crimping IGBT in bypass, power electronics afterwards on primary path is entirely controlled device and is disconnected, mechanical switch also starts to turn off, by the time mechanical switch closes have no progeny completely, crimping IGBT turns off, lightning arrester place in circuit suppresses short circuit current, this circuit breaker cut-offs speed, but the crimping IGBT of whole bypass bears voltage sum must be greater than DC power transmission line initial voltage, this needs a large amount of crimping IGBT series connection, cause the cost of whole DC circuit breaker higher.

And above-mentioned two kinds of patent major loops all must adopt full control switching device to connect with mechanical switch, still have larger conduction loss when causing normal.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, propose a kind of hybrid DC circuit breaker.It is low that the present invention has holistic cost, and during steady operation, loss is little, without arc cutting when there is short trouble, responds the features such as rapid.
