Embodiment
The utility model signal lighting protection type auto reclosing switch is made of two parts: auto reclosing switch and signal lighting protection module, auto reclosing switch comprise processor unit, voltage electric current detection of electrical leakage unit, line status detecting unit, operating state and alarm display unit, communication port; The signal lighting protection module comprises overvoltage discharge prevention device, overcurrent protector, two-way electrical surge absorber.The protection of power supply and the lightning protection of signal are organically combined, can prevent the accident tripping operation of power supply, effectively the guard signal line exempts from thunderbolt again, thereby better protection signal of base station transmission equipment is realized multiple function.
As depicted in figs. 1 and 2, a kind of signal lighting protection type auto reclosing switch 101 comprises reclosing switch and signal lighting protection module, the reclosing switch comprises supply line, electric brake 1, processor unit 2, voltage electric current detection of electrical leakage unit 3 and line status detecting unit 4, supply line is divided into power input 7 and power output end 8, voltage electric current detection of electrical leakage unit 3 be connected on after the power circuit input 7, be used to detect the real-time status of supplying power for input end circuit, line status detecting unit 4 is connected in parallel on before the power circuit output 8, be used to detect the real-time status of output circuit, the real-time status of the real-time status of input circuit and output circuit is sent to processor unit 2, send corresponding instruction after processor unit 2 is handled, control electric brake 1 carries out tripping or closure; Under trouble-free state, make electric brake 1 closure, line conduction at circuit; If circuit breaks down, then make electric brake 1 tripping, circuit disconnects; Processor unit 2 is CPU, and CPU is provided with independently control button 6 outward, and CPU can make by control button 6 and self accept the control come from the outside; Simultaneously, processor unit 2 also can connect display unit 5, is used for the real-time status of circuit and the alarm situation that processor unit 2 sends; Processor unit 2 also is provided with communication port 9, sends to long-range miscellaneous equipment such as the switch running status of electric brake 1, alarm data by communication port 9, simultaneously, by remote equipment the switch closure of electric brake 1 is controlled.Real-time status is divided into states such as " overvoltage ", " under-voltage ", " electric leakage ", " overload ", " short circuit ", " thunder and lightning ".
What be worth emphasizing is, the utility model has designed the signal lighting protection module, comprise overvoltage discharge prevention device 14, overcurrent protector 13, two-way electrical surge absorber 15, overcurrent protector 13 is connected on the holding wire between holding wire input 11 and output 12, is used to be switched on or switched off holding wire; Overvoltage discharge prevention device 14 and two-way electrical surge absorber 15 are connected with series system; the input of overvoltage discharge prevention device 14 inserts after the input of holding wire; the output head grounding of two-way electrical surge absorber 15, overvoltage discharge prevention device and two-way electrical surge absorber are used for the instant high-voltage on the holding wire is discharged into the earth.
The groundwork process of this signal lighting protection type auto reclosing switch is:
Before electric brake 1 closure, processor unit 2 by voltage electric current detection of electrical leakage unit 3 and line status detecting unit 4, come the real-time detection that the input/output terminal of whole circuit is correlated with.The content that detects mainly comprises: whether voltage is too high or low excessively, whether circuit exists electric leakage, failure conditions such as short circuit, overload whether occur.In case have failure condition in the discovery circuit, then processor unit 2 does not send reclosing command to electric brake 1, and electric brake 1 is not closed.Processor unit 2 shows relevant warning content by display unit 5.Then, processor unit 2 continues detection failure, makes a relevant analysis and gets rid of, and after fault-free, processor unit 2 sends reclosing command again, makes electric brake 1 closure, line conduction.
After electric brake 1 closure, processor unit 2 still detects in real time to circuit.Still have fault to exist after if find to close a floodgate or new fault occurred, then processor unit 2 is electric brake 1 rapid tripping, in case the fault effects on the power circuit input 7 is to power circuit output 8 and be connected on equipment on the line output 8.The process of repeating step one then.
When producing overvoltage or overcurrent owing to reasons such as thunders and lightnings on the holding wire, the signal lighting protection module can promptly be released the overvoltage signal to ground wire; When over-current signal occurring, lightning-protection module is the cut-off signal line promptly, prevents that effectively the heavy current signal from sealing in the transmission equipment.
When using usually, sort signal lighning proof type auto reclosing switch, power input 7 connect and exchange 220 input voltages, and power output end 8 is connected on the power end of base station equipment; The input 11 of holding wire is connected to the holding wire of antenna side, and the output 12 of holding wire is connected to the holding wire of base station transmits equipment side.When the normal fault-free of input voltage, the reclosing switch conduction is connected to the voltage of input on the output, provides power supply to base station equipment.Undesired or when thunderbolt is arranged when supply voltage, the auto reclosing switch deenergization, base station equipment temporarily has a power failure, with the protecting group station equipment, treat that supply voltage is normal after, automatic switch closes a floodgate again again, guarantees the base station equipment operate as normal.When because factor such as thunder and lightning and on holding wire, produce heavy current, when forceful electric power is pressed, signal lighting protection type auto reclosing switch is pressed signal ground with forceful electric power rapidly, and the cut-off signal line, make the heavy current signal can not seal in base station transmits equipment, guarantee the normal operation of communication equipment.
In sum, the utility model combines the protection of power supply and the lightning protection of signal, can prevent the accident tripping operation of power supply, and effectively the guard signal line exempts from thunderbolt again, better protection the signal of base station transmission equipment.Can timely and effectively supply line be judged automatically and control; and can realize remote monitoring; for distribution is wide, quantity is many, be difficult to the outdoor base station of manual supervisory Personal Handyphone System; not only can in the very first time, recover to close a floodgate; more can when taking place, unexpected failure condition initiatively trip; the protection electric equipment, and after fault is eliminated, can carry out automatic closing once more.Simultaneously, satisfied lightning protection (overvoltage) protection of AC power line and equipment preferably, discharging current is big, and the response time is fast, and its application prospect is good, economic benefit is very remarkable.
