Abstract
The utility model discloses a breaker contact overtemperature automatic alarm system, which is characterized by comprising a power supply circuit, a temperature sensor, a signaling conversion circuit and an alarm circuit. The power supply circuit is arranged on the contact wall of the breaker and is connected to the signaling conversion circuit; the temperature sensor is positioned at one side of the contact and is connected to the signaling conversion circuit through a high temperature lead; the signaling conversion circuit is connected to a wireless coding emitter; the alarm circuit is connected to the wireless decoding receiver; the wireless coding emitter is wirelessly connected to the wireless decoding receiver; and the output terminal of the alarm circuit is connected to six indicating lamps and alarms corresponding to the contacts. According to the alarm system provided in the utility model, an overheating accident of electric power equipment can be prevented, power supply reliability is raised, power failure loss is minimized, state maintenance can be achieved, in addition, abnormal heating loss can be minimized, an energy saving effect is provided, and the reasonable design and usage of electric power equipment are promoted.
Description
Technical field
The utility model relates to equipment for power transmission and distribution, particularly relates to a kind of contact of breaker overtemperature automatic alarm system.
Background technology
In shortage of electric power, load growth rapidly under the situation, the 10kV-35kV switch cubicle often owing to make or use, causes the temperature anomaly of contact to rise.If untimely discovery, untimely maintenance causes serious equipment breakdown sometimes.The major accident that causes of reason often is seen in newpapers and periodicals at home thus.For the serious accidents such as switch blast that prevent that contact temperature rise from causing unusually, more domestic producers and run unit adopt some to diagnose the temperature rise at other positions such as monitoring contact, bus like variable color sheet, infrared thermal imaging through regular meeting.But, these methods since exist deviation big, can not teletransmission or can't directly observe defective such as heat generating spot, can not be effective as a kind of preventive measure and promote.
According to the requirement of power industry technologies progress, switch cubicle develops to direction intelligent, non-maintaining, that possess self-diagnostic function, is developed to Condition-Based Maintenance Technology by original prophylactic repair.Develop a kind of economic, practical contact temperature rise automatic alarm system, under the prerequisite that does not reduce the existing equipment insulating property, the monitoring, alarming problem that solves the contact overheating is necessary very much.This device should be economical and practical, can not increase substantially the cost of switch cubicle, is convenient to the installation of new equipment and the transformation of old equipment again, improves security, the reliability of switchgear operation, reduces serious accident and take place.According to document announcement, the new product of some external High-Voltage Electrical Appliances manufacturers has been released the intelligent switchboard system that the band contact temperature measurement is reported to the police, but this product price is very expensive, there is no fear of a large amount of introductions.
Summary of the invention
To the problems referred to above, the utility model purpose is to provide a kind of economic, practical contact of breaker overtemperature automatic alarm system.
For reaching the problems referred to above; The technical scheme that the utility model proposes is: a kind of contact of breaker overtemperature automatic alarm system; It is characterized in that: comprise power circuit, temperature sensor, signaling conversion circuit and alarm circuit, described power circuit is installed in contact of breaker and touches on the wall, and connects signaling conversion circuit; Described temperature sensor is positioned at contact one side; And is connected described signaling conversion circuit connection wireless encoding transmitter, described alarm circuit connection wireless decoding receiver with signaling conversion circuit through high temperature wire; Described wireless encoding transmitter and the wireless connections of wireless decoding receiver, described alarm circuit output terminal connects six road pilot lamp and the alarm of the demonstration contact state corresponding with each contact.
In sum, adopt technique scheme, the monitoring system that the described contact of breaker overtemperature of the utility model automatic alarm system adopts corresponding electronic circuit, sensor, wireless transmitter to combine; Partly transform installation at original high-voltage circuit-breaker cart and form, transform the contact overtemperature monitoring system of assembling completion and want to accomplish six road handcart contacts are carried out on-line monitoring, do not influence primary cut-out original technique characteristic and insulation characterisitic again; Except preventing the power equipment overheat accident; Improve power supply reliability, reduce loss of outage, realize outside the repair based on condition of component; Can also reduce the abnormal heating loss; Play energy-saving effect, in addition, also help the appropriate design and the use of power equipment.
Description of drawings
Fig. 1 is the described contact of breaker overtemperature of a utility model automatic alarm system basic block diagram;
Wherein: 1. temperature sensor, 2. power circuit, 3. signaling conversion circuit, 4. the wireless encoding transmitter, 5. wireless decoding is sent out receiver, 6. alarm circuit, 7. six road pilot lamp, 8. alarm.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
As shown in Figure 1; A kind of contact of breaker overtemperature automatic alarm system; Comprise power circuit 2, temperature sensor 1, signaling conversion circuit 3 and alarm circuit 6, power circuit 2 is installed in contact of breaker and touches on the wall, and connects signaling conversion circuit 3; Described temperature sensor 1 is positioned at contact one side; And is connected described signaling conversion circuit 3 connection wireless encoding transmitters 4, described alarm circuit 6 connection wireless decoding receivers 5 with signaling conversion circuit 3 through high temperature wire; Described wireless encoding transmitter 4 and 5 wireless connections of wireless decoding receiver, described alarm circuit 6 output terminals connect six road pilot lamp 7 and alarm 8 of the demonstration contact state corresponding with each contact.
When specifically practical; When contact temperature heats up above safe temperature; Temperature sensor 1 is passed to signaling conversion circuit 3 with the overtemperature signal, and wire size change-over circuit 3 is passed to wireless decoding receiver 5 through wireless encoding transmitter 4 with the overtemperature signal, and wireless decoding receiver 5 is passed to alarm circuit 6 with the overtemperature signal; After alarm circuit 6 was received the overtemperature signal, alarm 8 began to report to the police.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; In form with on the details the utility model is made various variations, be the protection domain of the utility model.
