Abstract
The utility model discloses an alarm device for power-loss of a line, comprising two indicator lights, two fuses and a bell, wherein the indicator light HD is electrically connected with a normally open contact of a vacuum circuit breaker DL; the indicator light LD is electrically connected with a normally closed contact of the vacuum circuit breaker DL; the indicator light HD and the indicator light LD are connected with the power voltage in parallel; the bell HA is connected with the indicator light LD in parallel; two ends of the power voltage are respectively with the fuse RD1 and the fuse RD 2 in series; and the indicator light HD and the indicator light LD are respectively connected with a resistance R1 and a resistance R2 in series. By connecting the two indicator lights on the normally open and normally closed contacts of the vacuum circuit breaker, and at the same time connecting the bell with the normally closed contact, the normally electric shock of the vacuum circuit breaker is broken over, and the indicator lights are lightened and the bell alarms so as to timely inform the staff for maintenance when the circuit malfunctions.
Description
Technical field
The utility model relates to power supply station warning field, particularly, relates to a kind of alarm device that is used for the circuit dead electricity.
Background technology
At present, in order to ensure the safety of electricity consumption, existing power supply station all is equipped with vacuum circuit breaker, and when circuit broke down or have the people to get an electric shock, vacuum circuit breaker just can automatic cutout, to guarantee the safety of electricity consumption.But, wasted manpower because power supply station such as arrangement personnel 24 hours are on duty.And if unattended words can not in time be found fault, make circuit can not in time recover electric power.
The utility model content
The purpose of the utility model is, to the problems referred to above, proposes a kind of alarm device that is used for the circuit dead electricity, to be implemented under the unattended situation, can in time to find the advantage of fault.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of alarm device that is used for the circuit dead electricity; Comprise two pilot lamp, two fuses and electric bell; Said pilot lamp HD is connected electrically on the normally opened contact of vacuum circuit breaker DL; Said pilot lamp LD is connected electrically on the normally closed contact of vacuum circuit breaker DL, and said pilot lamp HD and pilot lamp LD are connected in parallel on the supply voltage, and said electric bell HA is parallelly connected with pilot lamp LD; The two ends of said supply voltage are in series with fuse RD1 and RD2 respectively, and said pilot lamp HD and pilot lamp LD are in series with resistance R 1, R2 respectively.
Further, said electric bell HA is in series with button SCL.
The technical scheme of the utility model vacuum circuit breaker often open with normally closed contact on be connected two pilot lamp, simultaneously on normally closed contact, be connected with electric bell, when circuit breaks down; The normally closed electric shock conducting of vacuum circuit breaker; Pilot lamp is lighted, and electric bell is reported to the police, and notifies personnel to keep in repair timely.
Further feature of the utility model and advantage will be set forth in instructions subsequently, and, partly from instructions, become obvious, perhaps understand through implementing the utility model.The purpose of the utility model can realize through the structure that in the instructions of being write, claims and accompanying drawing, is particularly pointed out and obtain with other advantages.
Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description below.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of instructions, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the described circuit theory diagrams that are used for the alarm device of circuit dead electricity of this utility model embodiment.
Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
As shown in Figure 1; A kind of alarm device that is used for the circuit dead electricity that the utility model provides comprises two pilot lamp, two fuses and electric bell, and pilot lamp HD is connected on the normally opened contact of vacuum circuit breaker DL through lead; Pilot lamp LD is connected on the normally closed contact of vacuum circuit breaker DL through lead; Pilot lamp HD and pilot lamp LD are connected in parallel on the supply voltage, and electric bell HA is parallelly connected with pilot lamp LD, and the two ends of supply voltage are in series with fuse RD1 and RD2 respectively; Pilot lamp HD and pilot lamp LD are in series with resistance R 1, R2 respectively, and wherein electric bell HA is in series with button SCL.Wherein the model of vacuum circuit breaker DL is ZN65A.
When communication disruption; The alarm device that is used for the circuit dead electricity; Be on the vacuum circuit breaker of circuit outlet switch; Get a subsequent use normal opened contact and seal in 220V (also can be the 36V direct current) power supply and a red led loop, get a normally closed contact again and seal in a 220V power supply and a green indicating lamp loop (this loop is electric whistle of parallel connection simultaneously) equally, just constituted a circuit dead electricity alarm device.When circuit broke down, the vacuum circuit breaker tripping operation caused the circuit dead electricity, and its normally closed contact is closed, and green indicating lamp is lighted and sent acoustic signal simultaneously, reminded the operator on duty of institute in time to search line fault.When the circuit normal power supply, its normal opened contact is closed, and red led is lighted, and reminds the operator on duty of institute, and line powering is normal.
The disclosed alarm device that is used for the circuit dead electricity of the utility model, when line switching tripped, the line management personnel can in time obtain notice.It is long so just to have shortened power off time, has improved power supply reliability.The power supply station unified at the station, the cable through 8 * 1.5 cores is installed to said apparatus in the duty room of power supply station.When communication disruption, this device can increase the reliability of unattended substation.Inclement weather particularly, the 10kV circuit that causes tripping more for a long time, the operator on duty of dispatching office wants one tunnel one tunnel announcement trunk managerial personnel; After this device has been arranged; The personnel of power supply station can just see the running status of circuit, so that exchange information with scheduling before the dispatching office notice.For in time taking corresponding measure to win the time, also equal to have won benefit.Can alleviate dispatching office person on duty's the tensity and the intensity that lessens fatigue to a certain extent.This device is a center of effort with practical, actual effect, is core content with equipment improvement, has informationization, robotization, interactive characteristic, and the equipment of power supply enterprise, personnel are optimized, and promotes the comprehensive utilization of manpower and device resource.
What should explain at last is: the above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
