Abstract
The invention discloses a low-voltage electrical parallel connection air circuit breaker of a transformer substation. The low-voltage electrical parallel connection air circuit breaker of the transformer substation comprises a processor and a connection and disconnection indicating module. The low-voltage electrical parallel connection air circuit breaker of the transformer substation is characterized in that the connection and disconnection indicating module comprises a switch device and a control circuit, the switch device and the control circuit are connected with two sets of three-phase binding posts, the control circuit is connected with an indicator light, a button, a display and the processor, one phase in each set of three-phase binding posts is connected with the processor, and the two sets of three-phase binding posts are connected with two sets of power sources. The low-voltage electrical parallel connection air circuit breaker of the transformer substation can automatically judge the cycle of the power sources, solve the problem that two sets of different power sources are automatically switched on in run-in period in a low-voltage substation in power utilization, have the functions of indication and prediction, and facilitate operation of operators.
Description
technical field:
The present invention relates to a kind of circuit breaker, particularly relate to a kind of transformer station low-voltage electrical air circuit in parallel.
background technology:
Transformer station's low-pressure section is to provide the power supply required for substation equipment, because transformer station provides this block supply, so station electricity consumption is very important, usually can get plural power supply point, for subsequent use each other, the reliability of interior power supply of guaranteeing to stand.
For achieving the above object, a power supply point is taken from station, and another is taken from outside station.Because institute's power taking source point may not be a system, its frequency may there are differences.When switching station electricity consumption at every turn, as needs parallel connection, must check two periods of whether same periods, if the same period just can carry out closing shunt trip breaker, this work is completed by manual measurement usually, troublesome poeration.
summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, there is provided a kind of structure simple, be easy to carry, can automatic decision power cycle, in solution low pressure station electricity consumption, two groups of different electrical power are from dynamic circuit connector phase combined floodgate problem, and have transformer station's low-voltage electrical air circuit in parallel of instruction, forecast function.
Technical scheme of the present invention is: a kind of transformer station low-voltage electrical air circuit in parallel, comprise processor, disconnected conjunction indicating module, described disconnected conjunction indicating module comprises switching device and control circuit, described switching device is connected with control circuit and two groups of three-phase binding posts, described control circuit is connected with indicator light, button, display and processor, described two groups of three-phase binding posts are respectively got a phase and are connected with processor, and described two groups of three-phase binding posts are connected with two groups of power supplys.
Described indicator light comprises indicator light and the non-synchronous indicator light same period, and described button comprises switch knob and opening button.
The invention has the beneficial effects as follows:
1, the present invention can automatic decision power cycle, to solve in the electricity consumption of low pressure station two groups of different electrical power from dynamic circuit connector phase combined floodgate problem, and has instruction, forecast function, the operation of handled easily personnel.
2, can not conducting loop when the present invention closes a floodgate when non-synchronous, avoid false switching to cause power supply short circuit accident, decrease the time of manual detection, be provided with indicator light and button simultaneously, avoid personnel's erroneous judgement and cause power supply short circuit accident.
3, the present invention is provided with display, can show the relevant information of access power supply, gives operating personnel prompting, prevents from carrying out misoperation.
accompanying drawing illustrates:
Fig. 1 is that transformer station's low-voltage electrical air circuit in parallel connects block diagram.
Fig. 2 is transformer station's low-voltage electrical air circuit structure chart in parallel.
embodiment:
Embodiment: see Fig. 1, Fig. 2, in figure, 1-three-phase binding post, 2-processor, 3-switching device, 4-control circuit, the 5-indicator light same period, 6-non-synchronous indicator light, 7-switch knob, 8-opening button, 9-display.
Transformer station's low-voltage electrical air circuit in parallel, comprise processor 2, disconnected conjunction indicating module, the disconnected indicating module that closes comprises switching device 3 and control circuit 4, switching device 3 is connected with control circuit 4 and two groups of three-phase binding posts 1, control circuit 4 is connected with indicator light, button, display 9 and processor 2, two groups of three-phase binding posts 1 are respectively got a phase and are connected with processor 2, and two groups of three-phase binding posts 1 are connected with two groups of power supplys.
Indicator light comprises indicator light 5 and non-synchronous indicator light 6 same period, and button comprises switch knob 7 and opening button 8.
During use, processor 2 calculates access signal, and the signal same period is issued disconnected conjunction indicating module, and the disconnected indicating module that closes judges, and perform corresponding operation by the corresponding operation of indicator light display, button, and show the information of access power supply on the display 9.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
