Abstract
The utility model discloses an overtemperature monitoring device of a high voltage switch cabinet, comprising a sandwiched temperature indicating wax sheet and an electronic nose which are arranged in the high voltage switch cabinet; the electronic nose is connected with a signal processing system which is connected with a control device; by adopting the technical proposal, no sensor is arranged at the electric-conducting part and no transmission guide line is needed, so as not to have safety hazards of the switch cabinet body; in addition, the electronic nose is only needed to be arranged at the inner side of the cabinet door, far away from an electrified part, the installation is convenient compared with the structure that specific points are needed to be arranged in the cabinet; the temperature indicating wax sheet and the internal material are non-conductive, the manufacturing cost is low, the appearance can be changed at any time along with the physical structure of the electric-conducting part, the monitoring level is improved and the construction is convenient and simple.
Description
Technical field
The utility model relates to a kind of monitoring device, specifically relates in a kind of closed high-tension switch cabinet that is applied in transformer station or power distribution room the high-tension switch cabinet temperature be carried out device for monitoring.
Background technology
Switch cubicle consumption in power supply department is very big, and along with the increase of user power utilization amount, the situation of switch cubicle overtemperature is more and more general, causes tremendous loss for power supply department, user, has influence on the safety of system even.Present most of low-tension switch cabinet does not adopt any surveillance equipment.The monitoring system that provides on the market has generally adopted the direct measurement of contact temperature, and system forms complicated, is not easy to install, and is difficult to large scale application.In fact, the brand of switch cubicle region of living in, switch cubicle, cooling condition, system loading and even switch cubicle residing physical location in transformer station all may have influence on the temperature of switch cubicle.Along with the attention of switch cubicle producer to its product technology, increasing switch cubicle develops towards the direction of compact conformation, maintenance safe.Existing system is installed complicated, has both increased the workload of installation work, has also introduced new trouble spot in switch cubicle.The previous very common way of order is, mounting temperature sensor in switch cubicle, but the relation of this way and experience is very big, possibly can't effectively monitor reliably switch cubicle if temperature sensor is installed in wrong position.
Summary of the invention
The purpose of this utility model provide a kind of easy for installation, and can reliably carry out the high-tension switch cabinet overtemperature monitoring device of temperature monitoring.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises sandwich temperature indicating wax disk(-sc) and the Electronic Nose that is positioned at high-tension switch cabinet, and Electronic Nose is connected with signal processing system, and signal processing system is connected with control device.
Above-mentioned sandwich temperature indicating wax disk(-sc) is positioned on the electric position of high-tension switch cabinet.
Above-mentioned Electronic Nose is positioned on the outer casing inner wall of high-tension switch cabinet.
Say that further Electronic Nose is connected with signal processing system by wireless network.
Above-mentioned control device is connected with alarm.
Adopt the utility model of technique scheme, need not any sensor be installed,, switch cubicle itself is not caused potential safety hazard also without any transfer wire at conducting position.In addition, Electronic Nose only need be installed in switch cubicle door inboard, away from charged position, than selecting specific point to install conveniently in cabinet.Temperature indicating wax disk(-sc) and inner material thereof are non-conductive, and cost is low, also can change its outward appearance at any time according to the conducting position physical arrangement, have improved the monitoring level, and easy construction.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises sandwich temperature indicating wax disk(-sc) 1 and the Electronic Nose 2 that is positioned at high-tension switch cabinet, described Electronic Nose 2 is connected with signal processing system 3 by wireless network, signal processing system 3 is connected with control device 4, and control device 4 is connected with alarm. and above-mentioned sandwich temperature indicating wax disk(-sc) 1 is purchased in commercially available.
Specifically, sandwich temperature indicating wax disk(-sc) 1 is sticked at each electric position of different conductions in switch cubicle, adheres to Electronic Nose 2 on the outer casing inner wall of high-tension switch cabinet.When this electric position local overheating takes place and reaches a certain design temperature, for example 80 ℃ the time, sandwich temperature indicating wax disk(-sc) 1 fusing, its inner material volatilizes specific gas, Electronic Nose 2 is smelt the back and is produced signal, and by wireless network the signal that produces is sent to signal processing system 3 and carries out information processing, the signal of handling is the most at last made last judgement by control device 4, judges with comprehensive whether current switch cubicle exists risk of overheating.When overheat condition appearred in switch cubicle, the alarm that is connected with control device 4 sent warning.
It is pointed out that and be to improve sensitivity, can consider that slippage speed to gas concentration as one of Rule of judgment, also can introduce thermometer as open condition.In case obviously improving appears in the gas concentration in the switch cubicle, and the temperature of switch cubicle improves rapidly, even there is accident potential in the not accidents caused inner overtemperature of switch cubicle that also may illustrate.After Electronic Nose 2 is sent signal, alarm equipment alarm, have a power failure and pull out switch inspection, the molten deformation place of wax is the potential faults point, and this point still can be used as basis for estimation after a period of time is left standstill in power failure.
