Abstract
The invention discloses a simple cable channel temperature and humidity monitoring and alarming device for a transformer substation. The device consists of a detection mechanism and an alarming mechanism, wherein the detection mechanism comprises a temperature sensor, a humidity sensor and a liquid level detection instrument; the alarming mechanism comprises a temperature sensor and a humidity sensor; the humidity sensor and the liquid level detection instrument are connected with the humidity sensor through a signal transmission line respectively; and the temperature sensor is connected with a temperature alarm through a signal transmission line. The alarming device can monitor the temperature and humidity of a cable channel of the transformer substation in real time, timely gives an alarm, effectively prevents a cable from being damaged so as not to cause equipment failure of the transformer substation, and ensures the normal operation of electric equipment.
Description
Technical field
The invention belongs to electric system detection technique field, particularly a kind of simple and easy transformer station cable duct humiture monitoring alarm.
Background technology
Along with the raising of automation of transformation substations level, all kinds of cables are more and more in the cable duct, and the operational management difficulty is also increasing, and it is more outstanding to carry out unattended transformer station problem.Because cable duct is distributed in battery limits and pulpit, relevant device is numerous, and the tour personnel are difficult to check one by one, if the cable overtemperature take place even catch fire, being difficult in the very first time finds, more difficultly in time adopts an effective measure, and causes equipment even personal injury accident.In addition, if transformer station's cable duct generation ponding, and the same no effective detection means of operational management personnel is found ponding, all kinds of cable long period of soaking cause insulation breakdown in water, cause equipment breakdown.
Summary of the invention
The invention provides a kind of real-time monitoring that can realize transformer station's cable duct temperature, humidity, and in time report to the police, effectively prevent cable bad and cause substation equipment fault, the simple and easy transformer station cable duct humiture monitoring alarm of the normal operation of support equipment.
Realize that the technical scheme that purpose of the present invention is taked is: this device is made up of detection agency and alarm mechanism, wherein detection agency comprises temperature sensor, humidity sensor and level detector, alarm mechanism comprises temperature sensor and humidity sensor, humidity sensor is connected with described humidity sensor by signal transmssion line respectively with level detector, and temperature sensor is connected with described temperature alarm by signal transmssion line.
Described temperature sensor, humidity sensor and level detector are connected with the wireless transmit element respectively, and described temperature alarm and humidity alarm are connected with the wireless signal receiving element respectively.
The simple and easy transformer station cable duct humiture monitoring alarm of making according to such scheme, can realize the real-time monitoring of transformer station's cable duct temperature, humidity, and in time report to the police, effectively the defense sector is ended cable bad and is caused substation equipment fault, the normal operation of guarantee electrical equipment.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, simple and easy transformer station of the present invention cable duct humiture monitoring alarm is made up of detection agency and alarm mechanism 7, wherein detection agency comprises temperature sensor 2, humidity sensor 5 and level detector 4, and be laid in each sensing point in the cable duct 1 respectively, can one or more groups temperature sensor, humidity sensor and level detector be set according to cable duct 1 segmentation humiture situation and monitoring needs.It is indoor that alarm mechanism is arranged on center monitoring, so that the operator on duty monitors.Alarm mechanism 7 comprises temperature alarm and humidity alarm and ponding alarm.When adopting the wire signal transmission between detection agency and the alarm mechanism 7, temperature sensor 2, humidity sensor 5 and level detector 4 are connected with the ponding alarm with the humidity alarm with described temperature alarm by signal transmssion line respectively.Confusion for fear of transformer station's internal wiring, described temperature sensor 2, humidity sensor 5 and level detector 4 are connected with wireless transmit element 3 respectively, described temperature alarm and humidity alarm are connected with wireless signal receiving element 6 respectively, realize transmission of wireless signals between detection agency and the alarm mechanism 7.In use, can rationally determine, install the humiture monitoring alarm of transformer station's cable duct 1 according to the effective coverage range of structure, environment and temperature sensor 2, humidity sensor 5 and the level detector 4 of cable duct 1; Set the upper limit value and lower limit value of report to the police temperature, humidity according to the designing requirement of cable duct 1; According to the upper limit value and lower limit value of reporting to the police at cable duct 1 bottom cable height setting ponding; Wireless transmit element 3 is installed in the cable duct 1, and it is indoor that alarm mechanism 7 can be installed in center monitoring.Respectively send early warning signal or alarm signal report to the police according to setting value to alarm mechanism by wireless transmit element 3,, send the fire alarm alarm signal when cable duct 1 temperature surpasses higher limit and humidity reaches down in limited time; When the super upper limit of cable duct 1 temperature and humidity at normal range Times overtemperature early warning signal; When ponding in the cable duct 1 (or other liquid) when reaching the early warning limit value, send the ponding early warning signal; When the ponding position reaches in limited time, send the ponding alarm signal; Prescribe a time limit when ponding reaches down, alarm signal is recovered.Reach thus and prevent cable bad and cause the substation equipment fault, the purpose of the normal operation of support equipment.
