Abstract
The invention relates to a terminal box used for connecting explosion proof type leading-out cables used for a large-scale motor. The terminal box comprises a junction box body and a cable sealing box, wherein three mutually closed terminal chambers are arranged in the junction box body, through holes are arranged on the rear walls and at the bottom parts of the terminal chambers, a sleeve pipe provided with a conducting rod and an end head and connected with a through hole on the rear wall of the junction box body in series is respectively arranged in the through hole on the rear wall of each terminal chamber to form a conducting rod channel, and pressure release discs are respectively arranged on the terminal chambers and the junction box body; the external cables are accessed from the cable sealing box and penetrate through the through holes at the bottom parts of the closed terminal chambers to be connected with the end head of the conducting rod on the sleeve pipe. Since the closed terminal chambers are arranged, the three-phase terminals are fully closed, and the insulating property is very reliable; meanwhile, even if the end head of the conducting rod is out of service and generates electric discharge, the generated heat causes the room pressure to rise, the pressure also can be released through the pressure release discs on the closed terminal chambers and the junction box body, so that the terminal box is prevented from exploding and various foreign substances are prevented from entering inside the motor, therefore, the safety of the motor is ensured.
Description
Technical field
The present invention relates to a kind of explosion-proof type outgoing cable connection terminal board that is used for large-size machine.
Background technology
Domestic existing large-size machine cable straight joint adopts rectangular cabinet mostly, in the rectangular cabinet cable straight joint three-phase bus bar is arranged, and two ends of three-phase bus bar support (busbar is fixed on the insulated terminal) by two insulated terminals respectively.The corresponding respectively end that is drawn out to busbar in the terminal box of motor threephase cable, the corresponding connection of the other end of busbar with outgoing cable.Do not have spacer assembly between terminal and between the three-phase outgoing cable, be prone to phenomenons such as air worsens, makes moist in the cable straight joint, the electric insulation reliability can not get guaranteeing.The domestic alternate discharge generation terminal board blast that causes and make foreign matter enter motor internal and discharge short over the ground, the major break down that causes motor to damage of once taking place to make moist several times.
Summary of the invention
The purpose of this invention is to provide a kind of easy-to-connect, attractive in appearance, electric property reliability height, what have explosion prevention function is used for the large-size machine terminal kit for cable coupling.
The present invention is combined by junction box body and cable sealing box two parts, is provided with three terminal chambers of sealing mutually in the junction box body, and its rear wall and bottom are equipped with through hole; Respectively there are a band conducting rod and the sleeve pipe of termination and the through hole of junction box body rear wall to wear connection in each terminal chamber rear wall through hole, form conductive channel; Terminal chamber and junction box body are equipped with pressure release dish; External cable inserts and passes the bottom through-hole of terminal chamber from the cable closure box and connects the cable connection that conducting rod tail end and motor are drawn with conducting rod termination on the sleeve pipe.
Because be provided with the blind end seed cell, make three-phase terminal complete closed, so insulation property are very reliable; Simultaneously, produce discharge even terminal sends fault, the heat of generation raises room pressure, also can be by the pressure release dish release pressure on blind end seed cell and the junction box body, avoid the generation of terminal board blast, also can avoid various foreign matters to enter motor internal, can guarantee the safety of motor.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is Figure 1A-A cutaway view.
1 is junction box body among the figure, and 2 is the terminal chamber, and 3 is sleeve pipe, and 4 is conducting rod and termination, and 5 is seal cartridge, and 6 is flange, and 7 is pressure release dish, and 8 is drier, and 9 is pressure release dish, and 10 is cable, and 11 is cable sealing box.
Embodiment
As shown in the figure, the present invention is combined by junction box body 1 and cable sealing box 11 two parts that steel plate welds, be provided with three terminal chambers 2 of sealing mutually in the junction box body 1, the terminal locular wall adopts epoxide resin material to make, junction box body and terminal chamber rear wall and bottom are equipped with through hole, the sleeve pipe 3 that passes terminal chamber rear wall through hole has seal cartridge 5, the sleeve pipe 3 of band conducting rod and termination is worn connection with the through hole of junction box body 1 rear wall, form conductive channel, sleeve pipe 3 is passed in the conducting rod termination, and to be positioned at terminal indoor, join with an end of external cable 10, the conducting rod tail end is big than the conducting rod termination, and screwed hole is arranged.The cable that has the copper threaded end that motor is drawn, from the through hole of junction box body rear wall penetrate with sleeve pipe the screwed hole of conducting rod tail end match and reliable fastening the connection, the two can conveniently shirk, change; Terminal chamber 3 and junction box body 1 respectively are provided with a pressure release dish, the concave disks that the pressure release dish 7 usefulness poured with epoxy resin on the terminal chamber become, and thickness is about 2mm, and is thinner than terminal locular wall, and general terminal chamber wall thickness is 7mm; The pressure release dish 9 of junction box body rear wall adopts the bakelite plate of 2mm to be installed in flange 6 inboard the getting final product of junction box body rear wall, and junction box body 1 is provided with silica gel drier 8, can keep the junction box body inner drying.When the generation discharge is broken down in the conducting rod termination, after producing certain heat internal pressure is raise, pressure release dish 7,9 on terminal chamber and the junction box body is broken through, terminal board inside is communicated with atmosphere, pressure reduces, thereby generation and the various foreign matter avoiding exploding enter motor internal, to guarantee the safety of motor.
