Abstract
The invention discloses a prewarning system of a high-tension switch cabinet, which comprises a system control host and a monitoring terminal, wherein the monitoring terminal is arranged opposite to the high-tension switch cabinet and connected with the system control host; and the monitoring terminal comprises a monitoring extension as well as a suction fan, a gas collecting module, a temperature sensor and an alarm device which are connected with the monitoring extension. According to the invention, small holes are arranged in tops of all chambers of the high-tension switch cabinet, air in all the chambers is exhausted by using the suction fan and detected, concentrations of gas components in the high-tension switch cabinet are analyzed through a physical mode for judging the heating conditions of devices in the cabinet body, and thus, the operation conditions of the devices in the high-tension switch cabinet are effectively monitored, and all the devices in the high-tension switch cabinet are covered. The popularization and the application of the prewarning system ensure that complete prewarning is possibly realized in the high-tension switch cabinet, and the key role in ensuring the safety operation of a power grid is played.
Description
Technical field
The present invention relates to a kind of failure detector, specifically a kind of high-tension switch cabinet early warning system.
Background technology
Along with mid-cabinet and the complete closed high-tension switch cabinet of operating mode are widely applied, the open type high-tension switch cabinet was progressively eliminated in recent years.The primary equipment heating of inner each air chamber of totally enclosed type high-tension switch cabinet and then to develop into the situation of accident in rising trend in actual motion.Owing to reasons such as device fabrication, environmental pollution, long-time running, serious overload operation, contact oxidation, electric arc impact cause contact resistance to increase; The continuous rising of temperature buried hidden danger to equipment safety operation when operation; Its material itself when being heated such as high-tension switch cabinet inside such as cable, all kinds of synthetic insulating materials can and distil along with the temperature rising; If untimely discovery causes device damage and short circuit accident easily, cause any property loss; Secondly the heating of cable overload seems particularly general in the area faster in load growth.Temperature is that a whether normal important parameter of characterization device operation particularly cut-offs contact point; Generally all there is an evolution if can detect the problem place in early days because the temperature of equipment rises, will makes operation and maintainer have time enough to keep in repair the accident of stopping and further enlarge.
High-tension switch cabinet is the important distribution facility of electric system; For the equipment in the totally enclosed type high-tension switch cabinet such as cable, cable end, disconnecting link contact, bus tie point etc.; How to detect these equipment heatings and still adopt the direct temperature measurement mode at present; Directly temperature-measuring part certainly will be installed on equipment as everyone knows to the equipment thermometric; Itself just there is accident potential in these parts of being installed, and limited point for measuring temperature can't cover the armamentarium in the high-tension switch cabinet, therefore can't the large scale investment actual motion.
Summary of the invention
To above-mentioned deficiency, the invention provides a kind of high-tension switch cabinet early warning system, its concentration through analysis high-tension switch cabinet composition of gases within is judged the heating situation of equipment in the cabinet, has monitored the equipment operation condition in the high-tension switch cabinet effectively.
For addressing the above problem, the present invention adopts following technical scheme: a kind of high-tension switch cabinet early warning system, it is characterized in that, and comprise system's main control system and monitoring terminal, the corresponding setting of said monitoring terminal and be connected with the system main control system with high-tension switch cabinet; Said monitoring terminal comprises monitoring unit and connected suction fan, gas collecting module, temperature sensor and alarm device;
Wherein, said suction fan is connected with the closed chamber of high-tension switch cabinet through gas pipeline, in order to gas in the high-tension switch cabinet is sampled; Said gas collecting module and temperature sensor all are arranged in the gas pipeline, gather gas componant and temperature data information in the gas pipeline respectively, and the data message of gathering is sent to monitoring unit; Said monitoring unit is handled the gas componant and the temperature data that receive, and the data message after will handling sends to system's main control system, simultaneously, early warning information is sent to alarm device carry out early warning.
Further, said monitoring unit is connected with the system main control system through the RS485 communication modes.
Further, also comprise the remote centralized management system, said system main control system is connected with the remote centralized management system through communication network.
The invention has the beneficial effects as follows: the present invention only need be provided with aperture in each chamber roof of high-tension switch cabinet; Utilizing suction fan that gas in each chamber is extracted out detects; And judge the heating situation of equipment in the cabinet through the concentration that physics mode is analyzed the high-tension switch cabinet composition of gases within, monitored the equipment operation condition in the high-tension switch cabinet effectively and contained the armamentarium in the high-tension switch cabinet cabinet.Of the present invention applying not only makes high-tension switch cabinet realize that comprehensive early warning becomes possibility, and to guaranteeing that electric power netting safe running has played key effect.
