The overtemperature alarm apparatus adopts centralized control, is high in management efficiency, adopts power supply in an induced electricity mode, and has a standby cell, and thus the overtemperature alarm apparatus is safe and reliable.

Description

A kind of switch cubicle inner cable joint excess temperature alarm device
Technical field
The utility model belongs to the temperature alarming technical field of power system device, is specifically related to a kind of switch cubicle inner cable joint excess temperature alarm device.
Background technology
In power industry, the conductor joint heating phenomenon often occurs in the power equipment in the substation operation, will cause serious industrial accident such as untimely discovery and processing.Enclosed switchgear is in operation and can not opens, and therefore is difficult to measure the actual temperature of cabinet nipple in service, and the serious threat electric power safety is produced.
Switch cubicle inner cable connector temperature is differentiated the following three kinds of modes of mainly taking at present: wax disk(-sc) thermometric, subjective thermometric and infrared survey.The defective that three kinds of conventional temp measuring methods all exist and are unfavorable for centralized control, human cost is high and thermometric can not continuous detecting, particularly the infrared sensor of infrared measurement of temperature method is fragile and maintenance workload is larger, can't dynamically grasp equipment running temperature situation of change, therefore, in this case, the technician of the industry wishes to develop the technical barrier that a kind of excess temperature alarm device solves present existence.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of switch cubicle inner cable joint excess temperature alarm device is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of switch cubicle inner cable joint excess temperature alarm device, comprise wireless temperature-measuring sensor, signal receiver, temperature monitoring, background computer and alarm, described wireless temperature-measuring sensor is packed on the interior cable splice of switch cubicle, and adopt the wireless transmission protocol mode to be connected with signal receiver, signal receiver is connected with temperature monitoring, temperature monitoring is connected with background computer by 485 buses, is connected with alarm by the I/0 interface.
And described wireless temperature-measuring sensor also is installed near the busbar of switch cubicle static contact or outdoor high-voltage switch position.
And the mounting means of described wireless temperature-measuring sensor is: be bundled on the cable splice after adopting stickup again.
And described wireless temperature-measuring sensor adopts induction power supply and the mutually standby common power supply mode of mode of battery.
Advantage of the present utility model and good effect are:
1, the utility model adopts the Radio Data-transmission technology, realizes the isolated high-voltage data transmission between high pressure point for measuring temperature and the temperature data acquisition device, adopts and exempts to apply for radio band, saves handling cost.
2, temperature sensing data processing unit and the wireless data transmitter spare of the utility model use all adopt the technical grade components and parts, can be 85 ℃ of high temperatures work, and the stability of device is strong.
3, the utility model adopts the induced electricity mode to power, and reserve battery is arranged, and is safe and reliable.
4, the utility model is beneficial to centralized control, and the efficiency of management is high, and cost is moderate.Solve temperature survey and overtemperature alarm problem in the switch cubicle, can be widely used in switch cabinet of converting station cable splice thermometric field.
Description of drawings
Fig. 1 is connection schematic block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described: it is emphasized that embodiment described in the utility model is illustrative, rather than determinate, can not limit protection domain of the present utility model with this.
A kind of switch cubicle inner cable joint excess temperature alarm device, comprise wireless temperature-measuring sensor, signal receiver, temperature monitoring, background computer and alarm, described wireless temperature-measuring sensor is packed on the interior cable splice of switch cubicle, and adopt the wireless transmission protocol mode to be connected with signal receiver, signal receiver is connected with temperature monitoring, temperature monitoring is connected with background computer by 485 buses, is connected with alarm by the I/0 interface.
In embodiment of the present utility model, sensor adopts induction power supply and the mutually standby mode of battery to power, the interval electric current of induction power supply work is between the 50A-5000A, install additional battery operated be interval below the 50A at electric current, per three wireless temperature-measuring sensors are one group and signal receiver wireless connections, three sensors of each group are installed in respectively near the busbar of switch cubicle static contact, switch cabinet outlet cable splice, the outdoor high-voltage switch position, the group number of required wireless temperature-measuring sensor is consistent with outlet cable splice interval quantity in the switch cubicle.
In embodiment of the present utility model, temperature monitoring carries signal receiver, and wireless temperature-measuring sensor and temperature monitoring be the army's of employing grade element all, can be at 125 degrees centigrade of lower steady operations of high temperature, and temperature-measuring range is between 0~200 ℃, and error range is less than 1 ℃; Transmission range 〉=600m(is unobstructed farthest).Temperature monitoring is installed on the switch cubicle, real-time display measurement temperature, and when temperature beyond limit, temperature monitoring triggers connected alarm by the I/0 interface and sends alerting signal.The temperature data of background computer Real-time Collection temperature monitoring, and temperature data preserved as historical record, be convenient to later assistant analysis.
