Abstract
The utility model relates to a record display device for the accident trip of a high voltage circuit breaker. The record display device is controlled by an intermediate relay and a circuit breaker and is connected with a record display through a spring contact point controlled by an operation mechanism for the circuit breaker. When an accident is generated, the intermediate relay is started by a relaying protection device, two normally open contact points of the intermediate relay close to turn on electricity to make the circuit breaker divide switches, the spring contact point is closed by the driving of the circuit breaker, the intermediate relay inputs an electric pulse to the record display, and the record display device records an accident trip. The utility model can record and display the accident trip of the circuit breaker automatically, which avoids the record error resulted from human operations and provides accurate opportunity for the maintenance of accidents.
Description
The utility model relates to a kind of record display unit of primary cut-out emergency stop valve trip, belongs to the annex of power system operation equipment.
For a long time, the primary cut-out emergency stop valve trip often takes place in electric power systems such as power plant, transformer station, and the generation of each emergency stop valve trip all needs manually to carry out manual statistic record, not only increased operational management personnel's labour intensity, and cause the mistake of statistics accident number of times and kind easily, delay the correct repairing time of circuit breaker, influence exerting oneself of circuit breaker, industrial production and people's lives are caused damage.
The purpose of this utility model provides a kind of can breaking down in electric power system, can write down the device that shows tripping operation number of times and kind automatically under the situation about the relaying protection action, so that operational management man analysis circuit breaker performance is also provided convenience for check.
The purpose of this utility model is achieved in that this circuit breaker emergency stop valve trip writes down display unit and controlled jointly by auxiliary relay and circuit breaker.Increase a spring contact in circuit breaker, this spring contact is by the operating mechanism control of circuit breaker.Be that branch, combined floodgate kinematic link in the circuit breaker operation mechanism is connected with spring contact 5 and controlled by this connecting rod.Spring contact disconnected when circuit normally moved.Auxiliary relay is connected with the protective relaying device of electric power system, starts auxiliary relay by protective relaying device when accident appears in circuit.The normally opened contact that auxiliary relay has two instantaneous make delays to open, the one tunnel is connected in series with the sensitive switch of circuit breaker, and connect with spring contact in another road.Protective relaying device sent signal to auxiliary relay when accident appearred in system; two normally opened contact closures; power to switching winding by sensitive switch for one; circuit breaker is finished the separating brake action under the effect of switching winding electromagnetic force; its operating mechanism drives the spring contact closure simultaneously; at this moment write down electric pulse of display unit energized input, this device counting once and by display unit shows.The automatic disconnection after closed a period of time of two normally opened contacts of auxiliary relay, its operating mechanism drives the spring contact disconnection behind the breaker closing, and the record display unit is finished a recording process and is restored to the original state, and prepares to continue to write down the next emergency stop valve trip of circuit breaker.Auxiliary relay can with the different types of circuit breaker emergency stop valve trip of different types of protective relaying device linkage record, for example overcurrent jumping, overvoltage jumping, zero sequence jumping etc.If protection malfunction tripping circuit breaker, this device also record once, available hand was dialled a numeral with display and sum is deducted was once got final product this moment.
Advantage of the present utility model is: this device can automatically write down number of times and the kind that shows the circuit breaker emergency stop valve trip, alleviated power system operation administrative staff's labour intensity, avoided causing artificially the error of circuit breaker emergency stop valve trip record number of times, and can to once, the secondary operational outfit plays the supervision effect.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the functional-block diagram of circuit breaker emergency stop valve trip record display unit;
Fig. 2 is the electric winding diagram of circuit breaker emergency stop valve trip record display unit.
Among the figure: 1. power supply 2. protective relaying devices 3. auxiliary relays
4. circuit breaker 5. spring contacts 6. record display devices
Among Fig. 1, protective relaying device 2 sends trouble signal starting auxiliary relay 3, and after the closing of contact of auxiliary relay 3, circuit breaker 4 separating brakes also drive snap switch 5 closures, makes record display device 6 and power supply 1 connect counting once.Be mechanical connection between circuit breaker 4 and the spring contact 5.
Fig. 2 is the electric winding diagram of this device.Two normally opened contact k1, k2 of auxiliary relay 3 are connected in series with the sensitive switch k3 and the spring contact 5 of circuit breaker 4 respectively, sensitive switch k3 links to each other with switching winding FQ, the operating mechanism of switching winding FQ and contact of breaker DL (not drawing among the figure) is connected to it provides power, make circuit breaker 4 separating brakes, its kinematic link drives spring contact 5 closures and makes record display device 6 connections behind the contact of breaker DL separating brake, and counting once.Auxiliary relay 3 is started by the circuit relay protection device, two normally opened contact k1, k2 automatic disconnections after time-delay a period of time of auxiliary relay 3.Its kinematic link drove spring contact 5 disconnections after contact of breaker DL closed a floodgate, and whole record display unit restores to the original state, and prepares record next time.
This primary cut-out emergency stop valve trip record display unit goes for the record and the demonstration of the various forms of circuit breaker emergency stop valve trip number of times of 10kv, 35kv, 110kv and above electric pressure, and the automatic management of electrical operation equipment is had positive effect.
