Abstract
The invention discloses a remote sudden stop control protection circuit. The remote sudden stop control protection circuit is characterized in that the protection circuit is formed by connecting a sudden stop control unit with an optical fiber signal receiving unit through two optical fiber channels, wherein the optical fiber signal receiving unit is used to control a power distribution control unit to cut off the preceding-stage power supply of high-voltage energy storage equipment. By adopting the above structure, the remote sudden stop control protection circuit of the invention has the following advantages that the whole circuit has advantage of simple design and good reliability, an optical cable has advantages of far transmission distance and fast transmission speed compared with an electric cable, and the optical cable will not be affected by external electromagnetic field and electromagnetic radiation. After the sudden stop and recovery sudden stop control switch is pressed, remote state acknowledgment can be performed, and the sudden stop control signal only can be recovered by manually recovering a circuit breaker in the high-voltage equipment field by testers so as to effectively ensure the safety of high-voltage energy source equipment and debugging workers.
Description
Technical field
The present invention relates to high voltage source and pulse-power apparatus, particularly a kind of long-range urgency is stopped control protection electric circuit.
Background technology
In pulse power industry and laser technology industry, along with the demand of system and device, high power, high voltage, high-octane power-supply device get more and more., because exist multiple devices to move simultaneously, and there is high-power component risk of explosion in a lot of high powers, high voltage installation device scene, tester often can not stay scene.The control room of general this extensive high-tension apparatus is by an independent room, or be arranged on place far away, once meet accident, operations staff can not be effectively from the power supply of source cutoff high equipment, if directly urgency is stopped to control, recover, again power up operation, tend to equipment to cause secondary to destroy.Secondly, operations staff in not clear field equipment state, if scene has commissioning staff to detect, and controlling run personnel again opening device power up operation, also can bring personal injury to commissioning staff.
It is generally by two kinds of modes, to realize anxious stopping to control that existing urgency is stopped control circuit, and a kind of is to control emergency stop switch, utilizes its normally-closed contact to control the zero line of power supply, realizes anxious stopping and controls; Another kind of by anxious input point of stopping control signal access PLC, utilize PLC program to control and interrupt its output relay or A.C. contactor.These two kinds of urgency are stopped control mode in the middle of practical application, have pros and cons separately, be not often very applicable in high power high-voltage energy storage equipment, can not timely and effectively control fast, the possibility that even there will be misoperation, in the certain risk of existence in service of high power high voltage energy storage device.
For the problems referred to above; provide a kind of novel long-range urgency to stop control protection electric circuit; under the state of emergency operations staff can be more fast, cutoff high energy storage device prime power supply timely; and can carry out remote status confirmation, can ensure on-the-spot high pressure energy device and commissioning staff's personal safety.
Summary of the invention
Technical problem to be solved by this invention is; provide a kind of long-range urgency to stop control protection electric circuit; under the state of emergency operations staff can be more fast, cutoff high energy storage device prime power supply timely; and can carry out remote status confirmation; can ensure on-the-spot high pressure energy device and commissioning staff's personal safety, to reach safe and reliable object.。
For achieving the above object; technical scheme of the present invention is; a kind of long-range urgency is stopped control protection electric circuit; it is characterized in that: described protective circuit is for the anxious control unit that stops is by two optical-fibre channels connection fiber-optic signal receiving elements, and fiber-optic signal receiving element is controlled the prime power supply of distribution control unit cutoff high energy storage device.
Described urgency is stopped control unit and is connected to feedback unit.
The two-way fiber-optic signal that described urgency is stopped control unit output is cascaded structure, and any road light signal interrupts being all defaulted as anxious stopping to be controlled.
Described distribution control unit comprises a fiber-optic signal dash receiver, and circuit breaker with shunt release forms, as long as receive and suddenly stop control signal, with regard to cut-off breaker, to reach cutoff high energy device current supply circuit.
Described urgency is stopped control unit and is provided with status indicator lamp HL1.
Long-range urgency is stopped a control protection electric circuit, owing to adopting above-mentioned structure, the invention has the advantages that design of integer electro-circuit is simple, can Gao Xinggao, and optical cable is than the long transmission distance of cable, and transmission speed is faster, and is not subject to the impact of external electromagnetic field and electromagnetic radiation.Anxious stop and recover after urgency is stopped control switch to carry out remote status confirmation pressing, and only have tester to recover circuit breaker at high-tension apparatus on-site manual, can recover anxious and stop control signal, thereby effectively ensure high pressure energy device and commissioning staff's safety.

Embodiment
The present invention is for the anxious control unit 1 that stops is by two optical-fibre channels connection fiber-optic signal receiving elements 2, and fiber-optic signal receiving element 2 is controlled the prime power supply of distribution control unit 3 cutoff high energy storage devices.Suddenly stopping control unit 1 is connected to feedback unit 4.
Specifically as Figure 1-4, the present invention includes anxious stop control unit 1, fiber-optic signal receiving element 2 and feedback unit 4 and high pressure energy device distribution control unit 3.Once there is emergency in high pressure energy device, take anxious stopping after control switch S1, suddenly stop control unit 1 and meet with a response, interrupt its two-way and suddenly stop controlling light signal D1 and D2.Fiber-optic signal receiving element 2 is not received after light signal, disconnects corresponding urgency and stops control relay, then disconnects the power distribution protection switch Q1 of the front controller in distribution control unit 3, thereby has reached the object of the prime power supply that disconnects high pressure energy device.Because the light signal in fiber-optic signal receiving element 2 belongs to the form of series connection, therefore, as long as acquiescence You Yi road light signal is lost, suddenly stop to control all effective.Meanwhile by fiber-optic signal D4, feed back to suddenly and stop control unit 1 and extinguish master control room status indicator lamp HL1, now suddenly stop to control to think effective.Now equipment state is abnormal, can not carry out operation with high pressure, and cannot the power supply of remote recovery high pressure energy device.In recovery, suddenly stop after control switch S1; illuminating state indicator light HL1 not; examine confirms that equipment state is normal; after can resuming operation; commissioning staff must manually recover the power distribution protection switch Q1 of front controller, at this moment can be fed back to suddenly and be stopped control box and light master control room status indicator lamp HL1 by light signal D4.Control room operations staff receives after useful signal, can recover the power supply of high pressure energy device, carries out normal High-Voltage Experimentation operation.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted technical solution of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
