In order to which those skilled in the art is made to more fully understand the technical solution of the utility model, below in conjunction with attached drawing and
Explanation is described in detail to the cable duct thermometric alarm system of the utility model in specific embodiment.
In cable duct thermometric alarm system provided by the utility model, by one section of cable duct by being divided into N between fire wall
A detection section, N are the natural number more than 1, and whole section of longer cable duct of length also is divided into the shorter detection of multiple lengths
Section, each length for detecting section make specific setting according to the environment at scene, and the utility model does not limit in detail herein.Because each
Detection section temperature in each section and differs all by being divided into relatively independent space between fire wall, in each detection section
Middle set temperature detection device 1 respectively, 1 signal of temperature-detecting device connect corresponding temperature controller 2 namely each temperature detection dress
It puts 1 and is correspondingly arranged a temperature controller 2, the actual temperature sensing detected in section is sent to temperature controller 2 by temperature-detecting device 1,
2 preset alarm temperature as needed of temperature controller, the inside of temperature controller 2 need 220V power supplys, and the inside of each temperature controller 2 connects respectively
Zero curve and firewire are connect, temperature controller 2 can be respectively arranged by battery limits terminal box, can also be by room or master control room is protected to concentrate peace
Dress control；Preset alarm temperature in temperature controller 2, when practical dut temperature is higher than alarm temperature, the relay in temperature controller 2 opens
Dynamic, normally opened temperature control contact 21 is closed, and can make this section of corresponding 4 cabling of alarm after the closure of temperature control contact 21 of temperature controller 2
It is alert, send alarm in time to staff, in order to be quickly found out the changed detection section of temperature, avoid delay reparation when
Between, it avoids that safety accident occurs.
As shown in Figure 1, the system construction drawing for cable duct thermometric alarm system provided by the utility model, wherein to divide
It is illustrated for being four sections, respectively A sections, B sections, C sections, D sections, KA represents intermediate relay 3, KA1~KA4 difference in Fig. 1
The intermediate relay different for four, difference corresponding A section~D sections, KA1 corresponding A sections, and so on；The inside difference of temperature controller 2
It is connected between zero curve N and firewire L, the temperature control contact 21 of temperature controller 2 is series at zero curve and firewire with the coil of intermediate relay 3
Between；The contact of intermediate relay 3 and alarm 4 are series between zero curve and firewire.When the temperature that temperature controller 2 receives is more than report
The temperature control contact 21 corresponding to it is closed during alert temperature, temperature control contact 21 is led with the circuit where the coil of intermediate relay 3
It is logical, and then the normally opened contact of intermediate relay 3 is closed, the corresponding alarm 4 of the detection section is made to power alarm.
Specifically, alarm 4 includes indicator light 41 in the utility model, and indicator light 41 is touched with the first of intermediate relay 3
Point 31 is series between zero curve and firewire.In Fig. 1, for A sections, corresponding temperature controller 2 be A temperature controllers, temperature control contact
21 be A contacts, and intermediate relay 3 is KA1, and the first contact 31 of KA1 is KA1-1, and KA1-1 and indicator light is series at zero curve
Between N and firewire L；B sections~D sections corresponding first contacts 31 respectively KA2-1, KA3-1, KA4-1, KA2-1, KA3-1, KA4-
1 respective one indicator light 4 of series connection, when 3 the first contact of power control 31 of intermediate relay is closed, makes corresponding indicator light light report
It is alert, visual alarm is sent out to staff.
Further, the alarm 4 in the utility model further includes alarm bell 42, the third of alarm bell 42 and intermediate relay 3
Contact 33 is series between zero curve and firewire.Third contact corresponding to A sections is KA1-3, alarm bell 42 of connecting on KA1-3, alarm bell
It is mainly used for sending out audible alarm to staff, provides staff note that therefore only needing to set in multiple and different detection sections
One alarm bell 42.
Preferably, the utility model, which is further included, is series at the second contact 32 of intermediate relay 3 between zero curve and firewire
The time relay 5, the delay break contact 51 of the time relay 5 is series on alarm bell 42 and the circuit of third contact 33；Prolong
When break contact 51 be normally-closed contact, the time relay 5 is powered, and start timing after the second contact 32 is connected, when the time after
More than after preset time, delay break contact 51 disconnects electric appliance automatically, releases alarm bell 42 and alarms, long-time jingle bell is avoided to cause not
Necessary interference, such as time of fire alarming is set as two minutes, staff can judge which section occurs by indicator light 41 after jingle bell
Problem, and overhauled at once, while need not also close alarm bell 42, the reaction time is saved, reaches alarm bell 42 after preset time
It is automatically closed, until the excessively high situation of temperature releases, 5 no power of the time relay, delay break contact 51 re-closes, in case
Alarm next time.Specifically, indicator light 41 and alarm bell 42 are installed in master control room in the utility model, in order to obtain sound simultaneously
Sound and visual alarm.2 temperature of temperature controller, for real-time display detects temperature.
Specifically, temperature-detecting device 1 is thermocouple, and thermocouple is set at the top of the inner wall of detection section or on side wall, often
Section thermocouple and temperature controller can set one, may also set up two or more.
When the practical dut temperature of thermocouple exceeds preset alarm temperature, the relay in temperature controller 2 starts, temperature control contact
21 are closed, and start intermediate relay 3, and by more than 3 a contact of intermediate relay, light warning and the delay of detection section is respectively started
Dynamic circuit breaker audible alarm, audible alarm can be arranged as required to the length of time of fire alarming, send signal to staff, make work
Personnel quickly learn which section cable duct goes wrong, and in order to quickly carry out inspection maintenance, maintenance are avoided to lead to safety not in time
Accident.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or new using this practicality
Type.A variety of modifications of these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice, can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
