Abstract
The utility model discloses a fire-proof and explosion-proof monitoring system, belonging to the technical field of an arc light protection system. The fire-proof and explosion-proof monitoring system comprises a detection unit, a transmission unit, a monitoring center and a nitrogen filling fire-proof and explosion-proof device. The detection unit is installed in an electric box and comprises an arc light sensor, a temperature sensor and a pressure sensor. The nitrogen filling fire-proof and explosion-proof device is respectively connected to the electrical box through pipelines. The detection unit is connected with the monitoring center through the transmission unit. The monitoring center is respectively connected with a breaker, an oil drain device of an oil storage tank and the nitrogen filling fire-proof and explosion-proof device of an electric box main connection line. The fire-proof and explosion-proof monitoring system has the advantages that a high temperature position caused by generated arc light or electric leakage is cooled rapidly, and a fire disaster caused by the explosion of a switchboard or a transformer due to high temperature and high voltage is avoided.
Description
Technical field
The utility model relates to a kind of supervisory control system, relates in particular to a kind of fire-proof and explosion-proof supervisory control system, is specially adapted to distribution board, the contour low tension gas tank use of transformer.
Background technology
Existing protection for inner arc faults such as switch cubicles; domesticly generally adopt transformer reserve overcurrent protection as main protection; because overcurrent protection is in order to guarantee its selectivity; its operation time limit need to cooperate according to the ladder principle; namely the operation time limit to mains side elongates step by step from load side; so that having arrived the main transformer place has reached 1.5-2.0 seconds; what have reaches 6 seconds especially; long fault clearing time like this; only have 100ms for the specified tolerance arc duration of switch cubicle, in case inner arc fault occurs, the damage of switching devices will be very serious; even produce blast and cause fire, Utilities Electric Co. or industry are suffered heavy losses.
Summary of the invention
For above-mentioned existing technical problem, the utility model provides a kind of fire-proof and explosion-proof supervisory control system, utilizes the transducer that is installed in electric box inside to come the running of sense switch and transformer.
The utility model is achieved through the following technical solutions for achieving the above object: a kind of fire-proof and explosion-proof supervisory control system, comprise detecting unit, transmission unit and Surveillance center, and also comprise nitrogen filling fireproof anti-explosion device; Detecting unit is installed in the electric box, comprises arc photosensor, temperature sensor and pressure sensor; Fuel reserve tank is inner to electric box by pipeline connection, nitrogen fill fireproof anti-explosion device by pipeline connection in the oil of electric box inside; Detecting unit is connected with the Surveillance center signal by transmission unit, and Surveillance center is electrically connected respectively the circuit breaker of electric box main electrical scheme, drainage device and the nitrogen of fuel reserve tank is filled fireproof anti-explosion device.
Operation principle of the present utility model: it is inner that arc photosensor is installed in the electric boxs such as distribution board or transformer, with the operational situation of sense switch and transformer; Transmission unit connects respectively arc photosensor, and temperature sensor and pressure sensor receiving the signal of operational situation, and are processed into detected value and are sent to Surveillance center; After Surveillance center receives the detection signal that is transmitted by transmission unit, compare with set point, judge whether detected value is unusual, if unusual, send enabling signal control circuit breaker trip, close the drainage device of fuel reserve tank, start nitrogen filling fireproof anti-explosion device, filling nitrogen in the electric box, so that nitrogen floats on the upper strata of electric box, the high temperature that on the one hand equipment fault is produced plays the rapidly effect of cooling, and nitrogen seals the top of electric box on the other hand, climbing sharply of compacting flame reaches fire-proof and explosion-proof effect.
The beneficial effects of the utility model are: utilize arc photosensor, pressure sensor or temperature sensor to detect, abnormal conditions occur, the escape circuit breaker is closed drainage device on the one hand on the one hand, and in electric box, fill the nitrogen fire extinguishing cooling, avoided the generation of Explosion of Transformer or fire; Warning system utilizes transmission unit to transmit to Surveillance center on the other hand, makes the operator on duty can immediately grasp the supervision situation of transformer or distribution board.
Description of drawings
Fig. 1 is electric theory diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises detecting unit, transmission unit and Surveillance center, also comprises nitrogen filling fireproof anti-explosion device.Detecting unit is installed in the electric box, comprises arc photosensor, temperature sensor and pressure sensor, the operational situation of detection. electronics.Transmission unit connects detecting unit, the test-accepting consequential signal, and adopt communication or directed RF-wise to transmit signals to Surveillance center.Fuel reserve tank is inner to electric box by pipeline connection, nitrogen fill fireproof anti-explosion device by pipeline connection in the oil of electric box inside.Surveillance center be electrically connected respectively the electric box main electrical scheme circuit breaker, fill fireproof anti-explosion device with the drainage device of fuel reserve tank and nitrogen.
The course of work of the present utility model: arc photosensor, temperature sensor, pressure sensor detects the operation conditions of each electronic installation in the electric box, and testing result is sent to delivery unit; Delivery unit receives arbitrary signal, reaches after treatment Surveillance center; Surveillance center is provided with comparing unit, judge according to set point whether detected value is unusual, if unusual, as: the phenomenons such as short circuit, defective insulation or electric leakage, generation arc light appear, then produce alarm signal and control circuit breaker trip, close the drainage device of fuel reserve tank, open simultaneously filling nitrogen in the oil of nitrogen filling fireproof anti-explosion device in the electric box, make nitrogen float on the electric box upper strata.The high temperature that produces of cooling failure rapidly on the one hand, sealing gland is in the top of transformer on the other hand, makes to produce the high temperature place that arc light or electric leakage cause and cool off rapidly, avoided HTHP to make distribution board or Explosion of Transformer and causes fire.
