Further, the junction box is simple in structure and low in manufacturing cost, maintenance frequency of the junction box can be decreased greatly, production efficiency of mines is improved, and safety production of the mines is guaranteed well.
Description
Technical field
The utility model relates to a kind of improvement of flame-proof mine low-voltage cable terminal box, specifically a kind of mine explosion-suppression high security type low-voltage cable terminal box.
Background technology
Flame-proof mine low-voltage cable terminal box plays an important role under mine, draws as the connection and the branch of cables such as well dynamic line, holding wire.Employed flame-proof mine low-voltage cable terminal box under mine at present; Comprise flame proof box body, junction block, cable ejector; The cable ejector can be established a plurality of; Junction block is fixed on the middle part in the flame proof box body, and the cable outside of drawing at junction block is provided with insulating case, and the existing deficiency of this flame-proof mine low-voltage cable terminal box is: in the safety in production process; Owing to cable length is long, widespread reason, flame-proof mine low-voltage cable terminal box somewhere can not confirm whether it is charged; If cable junctions loose contact or come off and cause phase shortage when electric switch detects phase shortage and reports to the police, maintenance personal's one a pair of each flame-proof mine low-voltage cable terminal box to open and inspect, easy-to-search accident point has not caused and has overhauled loaded down with trivial detailsly, wastes time and energy; If cable is long, resistance is excessive, causes heating and causes pressure drop; Cause whole loop current to reduce; When short circuit or electric leakage, electric current is not if reach electric switch earth leakage protective or short-circuit protection operating value, and then electric switch does not trip; That must cause whole loop current to increase, and burns the near-end terminal box; Owing at present do not have temperature detecting function in the flame-proof mine low-voltage cable terminal box of down-hole, can not in time eliminate the dangerous accident that the temperature that causes because of loose contact raises and causes.
Summary of the invention
The purpose of the utility model be to provide a kind of can in time overcome down-hole circuit phase shortage the time temperature at the loaded down with trivial details disadvantage of maintenance and butted line box contact place monitor, avoid burning the mine explosion-suppression high security type low-voltage cable terminal box of near-end terminal box in real time.
In order to reach above purpose; The technical scheme that the utility model adopted is: this mine explosion-suppression high security type low-voltage cable terminal box; Comprise flame proof box body, junction block, cable ejector; Junction block is fixed on the middle part in the flame proof box body, and the sheathed insulating case in the cable outside in that junction block is drawn is characterized in that: three-phase reactor/synchrotrans on the end top in the flame proof box body is fixing; At a side joint of three-phase reactor/synchrotrans the diode indicator light of three different colours is arranged, and stretch out from watch window; On the insulating case in the cable outside that junction block is drawn, fix radio temperature sensor.
The utility model is also implemented through following measure: the three-phase reactor in described three-phase reactor/synchrotrans is taken from the voltage cable on the junction block; 660V and 1140V all can, the synchrotrans in three-phase reactor/synchrotrans connect the diode indicator light of three different colours.
Described radio temperature sensor is fixed on the sheathed insulating case in the cable outside through band, can carry out the temperature acquisition of this point, and data are sent to the thermometric base station, carries out the macroscopic view monitoring.
The beneficial effect of the utility model is: this mine explosion-suppression high security type low-voltage cable terminal box; With at present under mine employed flame-proof mine low-voltage cable terminal box compare; Owing to increased phase shortage indication and temperature detection and reached the thermometric base station through wireless network; Carry out macroscopic view monitoring, thus significantly improved the safety in utilization of terminal box, and simple in structure, cheap, can significantly reduce maintenance frequency; Not only improve the production efficiency of mine, and guaranteed the safety in production of mine more.
