Fig. 2 is the circuit diagram of universal circuit breaker time delay take-off device of the present invention and no-voltage release.
Embodiment
For making above and other object of the present invention, feature and advantage can become apparent, cited below particularly go out preferred embodiment, and coordinate institute's accompanying drawings, be described in detail below.
Dead electricity can discharge at the drive lower armature of spring instantaneously, and then drive tripping mechanism action, air switch completes trip operation.During high tension distribution system lightning, if no-voltage release can take-off again after time delay a few second, after high-voltage system voltage momentary recovery is normal, electric power system can be maintained normal power supply, thus significantly reduces the impact that lightning produces lighter hydrocarbons facilities.
As shown in Figure 1, Fig. 1 is the circuit diagram of former no-voltage release, and in the circuit, no-voltage release 10 is directly connected in 400V alternating current.
As shown in Figure 2, Fig. 2 is the circuit diagram of universal circuit breaker time delay take-off device of the present invention and no-voltage release.This universal circuit breaker time delay take-off device comprises control transformer 21, DC rectifier circuit 22 and energy storage capacitor 23.High Level AC Voltage is become low-voltage AC by control transformer 21.In one embodiment, control transformer 21 is the control transformer of 50W, and 400V alternating current is become 24V alternating current.
DC rectifier circuit 22 is connected to control transformer 21, and the low-voltage AC that control transformer 21 exports is converted to low-voltage DC, and this low-voltage DC is supplied to no-voltage release 20.In one embodiment, DC rectifier circuit 22 is rectifier, and 24V alternating current is converted to 24V direct current.
Energy storage capacitor 23 is connected in parallel in the loop that DC rectifier circuit 22 and no-voltage release 20 form, and is that no-voltage release 20 is powered when lightning.In one embodiment, energy storage capacitor 23 is the energy storage capacitor of 2200uF.
Universal circuit breaker time delay take-off device of the present invention operationally, when there is lightning electric power system voltage instantaneous and losing, energy storage capacitor 23 discharges electric energy from trend no-voltage release 20, it is made to maintain attracting state, because air switch just can must trip after 5 seconds, within this 5 second, if electric power system can recover normal in time, then air switch can not trip, so just effectively can ensure the time delay of air switch take-off movement, recover normally until high-voltage system voltage, electric power system still can maintain normal power supply, avoid the generation that lightning causes the power-equipment stoppage in transit phenomenons instantaneously such as pump simultaneously, high-pressure system lightning will be significantly reduced affect lighter hydrocarbons facilities quantity-produced.
Universal circuit breaker time delay take-off device of the present invention, discharge for preventing high-pressure system lightning instantaneous loss of pressure release armature, change no-voltage release power supply into DC power supply, an energy storage capacitor in parallel on the coil, when system voltage is too low, electric capacity is from trend no-voltage release release electric energy, it is made to maintain the attracting state of certain hour, after energy storage capacitor electric discharge terminates, no-voltage release dead electricity, air switch completes time delay take-off operation automatically.The AC starting of the similar A.C. contactor of its remodeling method, direct current silent running, the mode of connection is simple, and reliability is high.
