Description
技术领域Technical field
本发明涉及高电压技术领域,并且更具体地,涉及一种用于触发间隙开关的直流大电流通流试验回路。The present invention relates to the field of high voltage technology, and more specifically, to a DC large current flow test circuit for triggering a gap switch.
背景技术Background technique
触发间隙开关是一种可用于交、直流系统的新型亚毫秒级快速关合开关,常与断路器并联作为快速控制/保护开关,触发间隙开关负责快速触发导、断路器随后合闸帮助间隙转移电流开始绝缘恢复。以白鹤滩-江苏±800kV直流工程可控自恢复消能装置控制用触发间隙开关为例,最低可触发电压20kV、通流要求30kA/30ms、绝缘恢复要求熄弧后1s可耐受DC80kV。The trigger gap switch is a new type of sub-millisecond fast closing switch that can be used in AC and DC systems. It is often connected in parallel with a circuit breaker as a fast control/protection switch. The trigger gap switch is responsible for quickly triggering the conductor and then closing the circuit breaker to help gap transfer. The current begins to restore the insulation. Taking the trigger gap switch for controlling the controllable self-restoring energy dissipation device of Baihetan-Jiangsu ±800kV DC project as an example, the minimum trigger voltage is 20kV, the current requirement is 30kA/30ms, and the insulation recovery requirement is that it can withstand DC80kV for 1 second after arc extinguishing.
触发间隙开关断口由固定不可以移动的高、低压电极构成,通过在间隙中燃弧来维持电流通路,短时通流大,电弧烧蚀可能会使触头烧损,同时产生大量金属蒸汽和气体分解产物,均会影响熄弧后快速绝缘恢复,需要开展通流试验,研究并验证大电流通流及绝缘恢复能力,通流试验回路是触发间隙开关研发及性能验证的重要手段。The fracture of the trigger gap switch is composed of high and low voltage electrodes that are fixed and cannot be moved. The current path is maintained by arcing in the gap. If the current is large in a short time, arc ablation may cause the contacts to be burned, and at the same time, a large amount of metal vapor and metal vapor are generated. Gas decomposition products will affect the rapid insulation recovery after arc extinguishing. It is necessary to carry out flow tests to study and verify the large current flow and insulation recovery capabilities. The flow test loop is an important means for the development and performance verification of trigger gap switches.
触发间隙开关的通流试验回路需要产生大电流,控制短时流过触发间隙开关后施加高幅值恢复电压,回路容量大,恢复电压高,控制复杂。目前,交流通流试验可以借助交流断路器短路开断试验用合成回路开展,直流通流试验还没有可用的试验回路,直接采用交流短路开断合成回路不能满足要求,需研究提出新的试验回路(包括电路拓扑、调控方法和设备参数确定方法等)。The flow test loop of the trigger gap switch needs to generate a large current, which is controlled to flow through the trigger gap switch for a short time and then a high-amplitude recovery voltage is applied. The loop capacity is large, the recovery voltage is high, and the control is complex. At present, the AC current test can be carried out with the help of a synthetic circuit for the AC circuit breaker short-circuit breaking test. There is no test circuit available for the DC current test. Directly using the AC short-circuit breaking synthetic circuit cannot meet the requirements, and new test circuits need to be researched and proposed. (Including circuit topology, control methods and equipment parameter determination methods, etc.).
交流短路开断试验用合成回路由低压大电流电流源和高压小电流电压源构成,通过电流源输出试验电流并控制燃弧时间,电压源通过球隙点火控制施加恢复电压。The synthetic circuit for the AC short-circuit breaking test is composed of a low-voltage large-current current source and a high-voltage small-current voltage source. The current source outputs the test current and controls the arcing time. The voltage source applies recovery voltage through ball gap ignition control.
上述回路用于触发间隙直流通流试验在以下几方面不满足要求:The above loop used to trigger gap DC flow test does not meet the requirements in the following aspects:
1)电流源输出电压通常只有10kV,低于最低可触发电压,触发间隙开关难以可靠触发导通,如果提升试验电压则会导致电源容量提高,大幅增加试验成本;1) The output voltage of the current source is usually only 10kV, which is lower than the minimum triggering voltage. It is difficult for the trigger gap switch to trigger conduction reliably. If the test voltage is increased, the power supply capacity will be increased and the test cost will be greatly increased;
2)电流源输出为交流电流,与直流燃弧存在一定的差异,交直流电弧的等价方法目前尚没有定论,如果将其改造为直流输出则需要增加大容量硅堆等整流设备,改造成本很高;2) The current source output is AC current, which is different from DC arc. The equivalent method of AC and DC arc has not yet been determined. If it is transformed into DC output, it will need to add rectification equipment such as large-capacity silicon stack, and the transformation cost will be high. very high;
3)试验回路依靠电流源支路辅助开关开断电流以控制燃弧时间,辅助开关在电流过零时才能熄弧开断,如果将电流源改造为直流输出则没有了电流过零点,辅助开关无法开断电流,导致无法控制燃弧时间。3) The test circuit relies on the auxiliary switch of the current source branch to interrupt the current to control the arcing time. The auxiliary switch can extinguish the arc and break when the current crosses zero. If the current source is transformed into a DC output, there will be no current zero-crossing point and the auxiliary switch will The current cannot be broken, resulting in the inability to control the arcing time.

下面结合实施例对本发明进行进一步的说明:The present invention will be further described below in conjunction with the examples:
本发明试验回路提供的试验回路电路拓扑如图1所示,本发明采用合成回路型式。The test loop circuit topology provided by the test loop of the present invention is shown in Figure 1. The present invention adopts a synthetic loop type.
电流源采用电容器组振荡放电加二极管续流的方式产生直流衰减电流,通过控制K1闭合时间选择隙燃弧时间;The current source uses the oscillating discharge of the capacitor bank and the freewheeling of the diode to generate DC attenuation current, and the gap arcing time is selected by controlling the K1 closing time;
电压源采用大容量直高发+MΩ级保护电阻实现熄弧瞬间施加指数上升恢复电压,通过控制电阻R及直高发输出电压选择恢复电压上升速率。两个支路的构成分别说明如下:The voltage source uses a large-capacity direct high-voltage + MΩ-level protection resistor to apply an exponential rise recovery voltage at the moment of arc extinction. The recovery voltage rise rate is selected by controlling the resistor R and the direct high-voltage output voltage. The composition of the two branches are explained as follows:
电流源支路由直流充电回路、能量泄放支路、储能电容器、续流二极管、电抗器、燃弧时间控制开关K1、保护开关K2、分压器Ⅰ和电流线圈组成。直流充电回路用于给储能电容器充电;能量泄放支路用于在回路设备异常情况下泄放储能电容器能量;储能电容器在间隙触通前提供试验电压,在间隙触通后提供大电流;续流二极管与储能电容反并联,与电抗器、触发间隙组成直流衰减电流回路;燃弧时间控制开关K1闭合后可转移触发间隙电流,从而控制燃弧时间;断路器K2用于在电压源给试品施加恢复电压时,隔离高压保护电流源回路设备;分压器Ⅰ用于测量试验电压;电流线圈用于测量试验电流。The current source branch is composed of a DC charging circuit, an energy discharge branch, an energy storage capacitor, a freewheeling diode, a reactor, an arc time control switch K1, a protection switch K2, a voltage divider I and a current coil. The DC charging circuit is used to charge the energy storage capacitor; the energy discharge branch is used to discharge the energy of the energy storage capacitor when the circuit equipment is abnormal; the energy storage capacitor provides a test voltage before the gap is opened and provides a large current after the gap is opened. ; The freewheeling diode and the energy storage capacitor are connected in anti-parallel, forming a DC attenuation current loop with the reactor and trigger gap; after the arc time control switch K1 is closed, it can transfer the trigger gap current to control the arc time; the circuit breaker K2 is used to control the arcing time when the voltage When the source applies recovery voltage to the test sample, isolate the high-voltage protection current source loop equipment; the voltage divider I is used to measure the test voltage; the current coil is used to measure the test current.
电压源支路由直流高压发生器、恢复电压调节电容和恢复电压上升时间调节电阻R和分压器Ⅱ组成。直流高压发生器用于给恢复电压调节电容充电,调节电容在间隙熄弧后提供恢复电压;电阻R阻值为MΩ级,在间隙通流时,限制直高发输出电流低于其短路保护电流,在间隙熄弧后与间隙断口杂散电容构成RC串联,控制间隙恢复电压的上升速率。The voltage source branch is composed of a DC high-voltage generator, a recovery voltage adjustment capacitor, a recovery voltage rise time adjustment resistor R, and a voltage divider II. The DC high-voltage generator is used to charge the recovery voltage adjustment capacitor, which provides recovery voltage after the arc is extinguished in the gap; the resistance R of the resistor is MΩ level. When the gap flows, the output current of the DC high-voltage generator is limited to be lower than its short-circuit protection current. After the arc is extinguished in the gap, it forms an RC series connection with the stray capacitance of the gap fracture to control the rising rate of the gap recovery voltage.
试验电路调控的具体方法如下,图2为仿真预期波形图;The specific method of test circuit control is as follows. Figure 2 shows the expected waveform diagram of the simulation;
试验前储能电容器组充电至试验电压U1,直高发输出升至恢复电压U2,K1断开、K2闭合。Before the test, the energy storage capacitor bank is charged to the test voltage U1, until the high-voltage output rises to the recovery voltage U2, K1 is opened, and K2 is closed.
0ms时控制触发间隙开关导通使电路连通,储能电容器组通过电抗器放电,如图2-(a),产生峰值I的振荡电流,如图2-(b)。At 0ms, the trigger gap switch is controlled to be turned on to connect the circuit, and the energy storage capacitor bank is discharged through the reactor, as shown in Figure 2-(a), resulting in an oscillating current with a peak value I, as shown in Figure 2-(b).
续流二极管的直流电流产生方法:当电流到达峰值时电容器组电压反向,续流二极管导通将电容器组旁路,如图2-(c),在间隙中产生直流衰减电流,如图2-(d)。The DC current generation method of the freewheeling diode: when the current reaches the peak value, the voltage of the capacitor bank is reversed, and the freewheeling diode is turned on to bypass the capacitor bank, as shown in Figure 2-(c), and a DC attenuation current is generated in the gap, as shown in Figure 2 -(d).
电抗器电流旁路的燃弧时间控制方法:根据通流时间需求控制K1在t时刻闭合,转移试验电流至“电抗器+K1”回路,既可以控制间隙燃弧时间,又不影响间隙施加恢复电压,如图2-(e)。电流转移原理为,K1闭合前,电流通路为“电抗器+续流二极管+K2+间隙”,其中间隙开关通过电弧维持电流通路,弧阻为几十~几百mΩ量级,续流二极管通态阻抗也在mΩ量级,K1闭合后,“电抗器+K1”回路阻抗为断路器合闸后触头接触电阻,阻值为几十~几百μΩ量级,远低于间隙+续流二极管支路电阻,因此,电流必将转移至K1支路,实现间隙燃弧时间控制。The arcing time control method of the reactor current bypass: control K1 to close at time t according to the current flow time requirement, and transfer the test current to the "reactor + K1" loop, which can control the gap arcing time without affecting the gap application recovery voltage, as shown in Figure 2-(e). The principle of current transfer is that before K1 is closed, the current path is "reactor + freewheeling diode + K2 + gap", in which the gap switch maintains the current path through the arc, the arc resistance is in the order of tens to hundreds of mΩ, and the freewheeling diode is on. The impedance is also on the order of mΩ. After K1 is closed, the "reactor + K1" loop impedance is the contact resistance of the contacts after the circuit breaker is closed. The resistance value is on the order of tens to hundreds of μΩ, which is much lower than the gap + freewheeling diode. branch resistance, therefore, the current will be transferred to the K1 branch to achieve gap arcing time control.
直流高压发生器的直流恢复电压快速施加方法:发出触发间隙开关触通指令同时控制断路器K2分闸,待电流被转移后触发间隙开关熄弧,同时K2断开直高发立即施加指数上升的恢复电压,如图2-(f),K2可以有效隔离电容器组免受恢复电压。这种方法的优点在于电源容量低,控制简单。选用较大容量直高发,间隙触通前,直高发给恢复电压调节电容充电至恢复电压,调节电容通过MΩ级恢复电压调节电阻R将高压施加到间隙上,此时K2处于分闸状态,将通流设备与直高发隔离保护;间隙触通后,直高发经调节电阻R接地,调节阻值应使接地电流低于直高发短路保护值使直高发保持高压输出;间隙熄弧时,调节电容经调节电阻R给间隙断口施加指数上升的恢复电压,通过选择合理调节电容容值,使恢复电压上升时间不受开关K2断口和间隙断口电晕放电影响,仅由调节电阻R和断口杂散电容决定,可以达到ms量级,满足触发间隙开关需要。The DC recovery voltage rapid application method of the DC high voltage generator: issue a command to trigger the gap switch and control the circuit breaker K2 to open at the same time. After the current is transferred, the gap switch is triggered to extinguish the arc. At the same time, K2 is disconnected and the direct high voltage is immediately applied to restore the exponential rise. voltage, as shown in Figure 2-(f), K2 can effectively isolate the capacitor bank from recovery voltage. The advantages of this method are low power capacity and simple control. Choose a larger-capacity direct high-voltage generator. Before the gap is triggered, the direct high-voltage generator charges the recovery voltage adjustment capacitor to the recovery voltage. The adjustment capacitor applies high voltage to the gap through the MΩ-level recovery voltage adjustment resistor R. At this time, K2 is in the open state, and the The flow-through equipment and the direct high-voltage generator are isolated and protected; after the gap is connected, the direct high-voltage generator is grounded through the adjusted resistor R. The resistance value should be adjusted so that the ground current is lower than the short-circuit protection value of the direct high-voltage generator so that the direct high-voltage generator maintains high-voltage output; when the gap is extinguished, The adjusting capacitor applies an exponentially rising recovery voltage to the gap fracture through the adjusting resistor R. By selecting a reasonable adjustment of the capacitance value, the recovery voltage rise time is not affected by the corona discharge at the switch K2 fracture and the gap fracture. It is only controlled by the adjusting resistor R and the fracture surface. Determined by the loose capacitance, it can reach the ms level and meet the needs of triggering gap switches.
根据某地直流工程触发间隙开关通流试验要求,设计直流通流试验回路,试验电压U1=30kV,试验电流峰值I=30kA,燃弧时间t=80ms,恢复电压U2=80kV,上升时间100ms,全面满足了试验要求,电流源支路中储能电容器额定电压36kV、电容值1mF、电抗器电感值0.78mH;电压源支路中直高发额定电压-160kV、额定电流10mA,电阻R阻值30MΩ。结果表明试验回路电源容量小、调节简单方便,可以经济有效的满足触发间隙开关通流试验需要。According to the requirements for triggering the gap switch flow test of a certain DC project, the DC current test circuit is designed.
