The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical solutions of the utility model, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the claimed scope of the utility model.In the middle of these accompanying drawings,
Fig. 1 is the schematic diagram of the utility model embodiment 1;
Fig. 2 is the schematic diagram of the utility model embodiment 2.
Among the figure: 1-electric brake; 2-processor unit; 3-voltage electric current the detection of electrical leakage unit; 4-line status detecting unit; 5-display unit; 6-control button; 7-line input; 8-line output; 9-communication port; 10-base station.
Embodiment
As depicted in figs. 1 and 2, a kind of automatic coincidence electric brake protection switch, comprise 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 input 7 and output 8, voltage electric current detection of electrical leakage unit 3 be connected on after the 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 line 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, after handling, processor unit 2 sends corresponding instruction, control electric brake 1 carry out tripping or closure: at circuit under trouble-free state, make electric brake 1 closure, line conduction; If circuit breaks down, then make electric brake 1 tripping, circuit disconnects.Processor unit 2 can be 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.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.
As shown in Figure 1, a kind of automatic coincidence electric brake protection switch, comprise 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 input 7 and output 8, voltage electric current detection of electrical leakage unit 3 be connected on after the 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 line 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, after handling, processor unit 2 sends corresponding instruction, control electric brake 1 carry out tripping or closure: at circuit under trouble-free state, make electric brake 1 closure, line conduction; If circuit breaks down, then make electric brake 1 tripping, circuit disconnects.
The groundwork process that should overlap the electric brake protection switch automatically is:
Step 1: 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.
Step 2: 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 line input 7 is to line output 8 and be connected on equipment on the line output 8.The process of repeating step one then.
This automatic coincidence electric brake switch can be positioned in the middle of the equipment of line input 7 and PHS base station 10, the output of control power supply.Under the normal situation of circuit, the electric current of line input 7 input 220V voltages makes the equipment normal operation work of PHS base station 10; Because overvoltage, under-voltage, electric leakage, overload, short circuit etc. cause after the tripping operation, processor unit 2 in time detects, gets rid of, and can carry out automatic closing in the very first time, need not manual operation when power supply.When too high or too low, load overload or short circuit appearred in supply voltage, overlapping the electric brake switch automatically can automatic trip, cut off the electricity supply, and guaranteed that communication equipment is can be because of power supply not former thereby cause damage.Should overlap lightning protection (overvoltage) protection that the electric brake switch can satisfy AC power line and equipment automatically, and discharging current is big, the response time is fast; Moreover the power failure alarm indication is on panel, and effect is directly perceived, and failure cause comes into plain view.
As shown in Figure 2, on the basis of embodiment 1, processor unit 2 can further be 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.Its groundwork process is similar to Example 1, repeats no more.
In a word; the utility model can be judged supply line and control timely and effectively automatically; 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.Like this, under the prerequisite that guarantees supply line's reliability service, improved operating efficiency greatly.
