Abstract
The utility model discloses a power equipment overheating fault alarming signal remote monitor through optical fibers. A reflector (6) is enchased on a dynamic display panel (3) of the original equipment overheating fault monitor, emitting fibers (7) and receiving fibers (8) are set on a support (2), the equipment monitored point is overheating, the dynamic display panel (3) lodges and the receiving fibers (8) send out alarming light signals. Because the optical fibers is insulated and the length can be setup based on demand, thus the isolation from the high voltage environment of the power equipment monitored point to the safe environment.
Description
One, technical field:
The utility model relates to a kind of apparatus overheat fault monitor, specifically, is a kind of monitor that utilizes fiber optic conduction temperature overheating alerting signal.
Two, background technology:
The background technology relevant with the utility model is that my patent No. is 02289424 " apparatus overheat fault monitor ", this device is installed on the contact in the high voltage electric power equip ment, contact temperature just often, moving display board uprightly with decide display board and overlap, in case contact is overheated, when surpassing the warning working point that is provided with, moving display board lodging, with decide display board and become 90 ° of crossing condition, the operator on duty can find this contact generation overheating fault by making an inspection tour, thereby makes fault obtain handling, to avoid burning power equipment, cause large area blackout.
Practice shows, though said apparatus can be finished warning function, also can clear display alarm state, and this all is to need frequent manual patrol could realize, and is difficult for the place (in switch cubicle) of observations for some, manual patrol is just more difficult.
Three, summary of the invention:
The technical problems to be solved in the utility model provides the overheating fault monitor that the monitor status signal that a kind of energy will be installed in the high-pressure area (normal or report to the police) took out and delivered to the safety zone; this status signal can carry out sound and light alarm by the subsequent conditioning circuit of safety zone; teletransmission is also imported computing machine and is handled, thereby reaches the more convenient whether purpose of operate as normal of high-voltage contact of observe understanding in time.
For solving the problems of the technologies described above, concrete scheme of the present utility model is as follows:
The utility model is by metab, support, moving display board, decide display board, temperature-sensitive switch, catoptron, form, catoptron is embedded on the moving display board of above-mentioned overheated monitor, launching fiber places on the relative support in catoptron the place ahead with reception optical fiber, when the power equipment contact that is monitored is working properly, moving display board is upright, the optical fiber that the self-emission pipe sends is by launching fiber, mirror reflects is to receiving optical fiber, send into receiving tube through receiving optical fiber again, the light that receiving tube is subjected to reflected back produces corresponding marking current, amplify through amplifier, drive green luminotron, show that this point is working properly, as monitored some generation overheating fault, in case temperature rises to designed warning working point, moving display board lodging, reflected light is blocked, and receiving tube does not have electric signal output, and the green luminotron of amplifier out extinguishes, red luminotron flicker, the news Chinese percussion instrument alerting signal of sounding simultaneously.
Because optical fiber has high pressure resistant, the anti-electromagnetic field characteristics of interference, the length of optical fiber can be selected according to on-the-spot needs, so, we can place the low-voltage safety area with emission, receiving tube and amplifier, and will place the light signal of the overheated monitor alarm condition of high voltage, big current work environment by optical fiber, and be sent to the safety area, realize the remote monitoring that high voltage environment is crossed hot junction.
Four, description of drawings:
Fig. 1 is the utility model one-piece construction synoptic diagram:
Among the figure, 1 is metab, and 2 is support, and 3 are moving display board, and 4 for deciding display board, 5 is temperature-sensitive switch, and 6 is catoptron, and 7 is launching fiber, and 8 for receiving optical fiber, and 9 is power valve, 10 is receiving tube, and 11 is amplifier, and 12 is green luminotron, and 13 is red luminotron, and 14 are the news Chinese percussion instrument.
Five, embodiment:
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is elaborated.
As can be seen from Figure 1, catoptron 6 is embedded in the front lower place of moving display board 3, launching fiber 7 is installed on the relative support 2 in catoptron 6 the place aheads with reception optical fiber 8, and launching fiber 7 extends to the safety area with reception optical fiber 8 and links to each other with receiving tube 10 with power valve 9 respectively.
When monitor is in normal operating conditions, moving display board 3 is upright, the light that is sent by power valve 9 incides on the catoptron 6 by launching fiber 7, be reflected into simultaneously and receive optical fiber 8, receive optical fiber this reflected light signal is delivered to receiving tube 10, become corresponding electric signal, amplify by amplifier 11, it is luminous to drive green luminotron 12, and it is a little working properly to show that this is monitored.
In case it is overheated that the monitoring point takes place, temperature surpasses the warning working point, moving display board 3 lodging, catoptron 6 breaks away from original light reflex circuit, receives the light signal that received originally in the optical fiber 8 and is blocked, receiving tube 10 no light signal outputs, amplifier 11 output terminal green luminotrons 12 extinguish, red luminotron 13 flicker drives news Chinese percussion instrument 14 alerting signal of sounding simultaneously, shows that this is monitored an overheating fault takes place.
The another kind of embodiment of Fig. 2:
Different with last embodiment is, reflection with light signal in this example changes the correlation structure, launching fiber 7 lays respectively at moving display board 3 with reception optical fiber 8, decides display board 4 both sides and in opposite directions concentric, when contact is working properly, moving display board 3 is upright, receiving optical fiber 8 receives the emission light signal and is transferred to receiving tube 10, green luminotron 12 is luminous, shows that contact is working properly, when overheated, moving display board 3 lodging, the light path blocking-up, green luminotron 12 extinguishes, red luminotron 13 flickers, news Chinese percussion instrument 14 is reported to the police, and shows that contact is in the fault alarm state.
