Abstract
A simulated breaker mainly comprises a power supply (1), buttons (2) and secondary luminotrons (3), wherein the power supply (1) is externally connected with two loops, one loop is provided with a switching-on contact, a normally-closed contact and a switching-on loop, an upper end of the switching-on contact is provided with a button (2), a lower end of the switching-on contact is connected with a secondary luminotron (3), the switching-on loop is serially connected with two resistors (7) and then is parallelly connected with a capacitor (6), the other loop is provided with a trip contact, a normally-open contact and a trip loop, an upper end of the trip contact is provided with a button (2), a lower end of the trip contact is connected with a secondary luminotron (3), and the trip loop is serially connected with two resistors (7) and then is parallelly connected with a capacitor (6). Beneficial effects of the simulated breaker are that the simulated breaker can replace a vacuum circuit breaker, and is fast in operation and sensitive in reaction.
Description
Technical field
The utility model relates to a kind of when power industry is done protection test, is used for the mimic-disconnecting switch that the debugging of high-low pressure microcomputer protecting device is used.
Background technology
At present power industry all is being with vacuum circuit breaker to do when doing the test of robotization Microcomputer Protection at the scene, and vacuum circuit breaker has the life-span, and generally also just deciliters several thousand times, and the Microcomputer Protection test all will be done once equipment ability safe operation like this every year.A protection test possibly need deciliter isolating switch tens times even more; Thereby the brief serviceable life of isolating switch is if when proofreading and correct protection test, can substitute vacuum circuit breaker with this microsimulation isolating switch earlier; Simple to operate, can reach each item function of verifying Microcomputer Protection equally.Some protection producers also can utilize this microsimulation isolating switch to debug the Microcomputer Protection of production.It is convenient and simple to operate, also very practical.
The utility model content
The utility model technical matters to be solved provides a kind of a kind of novel analog short-circuiting device that can replace protective device on the large scale circuit that is applied in the power industry.
The utility model principal feature is: mainly by power supply, button, diode luminescence pipe constitute, and power supply connects two groups of loops outward; One combined floodgate contact is set on one group of loop; One normally closed contact, Yi Hequan, its combined floodgate contact upper end is provided with a button; The lower end connects a diode luminescence pipe, and it closes a parallelly connected electric capacity behind circle series connection two resistance; Another group is provided with a tripping operation contact on loop, a normal opened contact, and one jumps circle, and its tripping operation contact upper end is provided with a button, and the lower end connects a diode luminescence pipe, and it jumps a parallelly connected electric capacity behind circle series connection two resistance.
The beneficial effect of the utility model is: this device can well substitute vacuum circuit breaker, and action is fast, is quick on the draw.
