Description
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 guaranteeing direct current transmission and distribution system and direct current network system stability safe and reliable operation.With AC system difference being, there is not natural zero-crossing point in the electric current of direct current system, so in direct current system, cannot as AC system, utilize the natural zero-crossing point of electric current to turn-off, so the problem of cut-offfing of direct current is a problem that is worth research always.
Breaking direct current has two kinds of modes conventionally at present, and the first is pure power electronics circuit breaker, and the patent CN102870181A as ABB application, utilizes the high-power power electronic device of turn-offing, directly disjunction direct current.The solid circuit breaker that utilizes this principle to manufacture, although can meet in time the requirement of multiterminal flexible direct current system, the loss when normally is excessive, economy is poor.
The second is to mix circuit breaker technology, on the basis of traditional interchange mechanical chopper, by increasing auxiliary Power Electronic Circuit, drop into current-limiting resistance with reduce short circuit current or on the direct current that cut-offs arc gap superimposed oscillation electric current, while utilizing current over-zero, cut-off circuit.The hybrid circuit breaker that utilizes this principle to manufacture, it has specific (special) requirements to mechanical switch, the more difficult requirement that meets DC transmission system on break-time.
A kind of mixing circuit breaker that Siemens patent WO2013/093066A1 proposes, connect on primary path mechanical switch and power electronics controlled device entirely, another bypass is comprised of electric capacity, when fault current being detected, on primary path, power electronics is controlled device disconnection entirely, mechanical switch also starts to cut-off, fault current charges to shunt capacitance, the shunt capacitance of sort circuit is can not value too small, otherwise mechanical switch is opened not yet completely, if shunt capacitance voltage under fault current charging rises, too fast meeting surpasses mechanical switch and power electronic device is born electric pressure.When yet capacitance value is large, the speed of cut-offfing will be affected.
A kind of mixing circuit breaker that the patent WO2011141054A1 of ABB AB proposes, connect on primary path mechanical switch and power electronics controlled device entirely, another bypass is composed in parallel by lightning arrester and crimping IGBT, when fault current being detected, the whole conductings of crimping IGBT in bypass, power electronics on primary path is controlled device disconnection entirely afterwards, mechanical switch also starts to turn-off, by the time mechanical switch completely closes and has no progeny, crimping IGBT turn-offs, lightning arrester place in circuit suppresses short circuit current, this circuit breaker cut-offs speed, but bearing voltage sum, the crimping IGBT of whole bypass 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.
