Abstract
The utility model relates to a low-voltage high-capacity flameproof motor terminal box, which comprises a casing body. Wiring bolts are fixedly installed at the bottom of the casing body through an installing plate; two terminal posts are arranged at one end of each wiring bolt; a terminal box cover with a flameproof surface is mounted on the upper portion of the casing body through a fastening part; heating tape lead wires are installed inside the casing body; and a heating tape wire outlet is led out on the lower portion in the middle of a main wire outlet. The terminal box adopts the structure that six wiring bolts are connected with twelve lead wire terminal posts, thereby decreasing the cross sectional area of motor lead wires and effectively guaranteeing electric clearances and creep distances inside the terminal box. Simultaneously, heating tape connection wires are arranged inside the terminal box so as to enable the structure inside the terminal box to be more compact, overall volume of the terminal box is greatly reduced, and harmony between the terminal box and a motor base is enhanced.
Description
Technical field
The utility model belongs to motor appurtenances technical field, is the big capacity explosion-proof motor of a kind of low pressure terminal box.
Background technology
In technique known, the main difficult point of the big capacity explosion-proof motor of low pressure design is the design of terminal box, because capacity is big, so that phase current reaches the load that lead wire bears greatly is all very big.With the 560kW-4 motor is example, if press 6 pin configurations of prior art, the sectional area of every lead wire need reach 310mm
2More than, such lead-in wire is too slightly too hard, can't use in motor.Design routinely, the lead wire of motor internal generally is no more than 120mm
2, therefore need change 6 lead-in wires is 12 pin configurations, like this, every lead-in wire sectional area has only 95mm
2Though, can solve the thick excessively problem of lead-in wire,, need 12 connection bolts to match.Yet, because electric clearance in the explosion--proof regulations butted line box and creepage distance have strict regulation, therefore certainly will cause the terminal box volume excessive, not only increase cost, and terminal box and motor size are inharmonious, even cause difficulty is installed, and bring profile not attractive in appearance simultaneously, drawbacks such as terminal block inconvenience, this problem is solved at present as yet preferably.
The utility model content
The purpose of this utility model provides a kind of compact conformation, and volume is little, cost is low, the big capacity explosion-proof motor of the low pressure of easy-to-connect terminal box.
Realize that the technical scheme that the purpose of this utility model is taked is: this terminal box has a housing, the bottom of housing is fixed with the connection bolt that an end has two binding posts by mounting panel, the connector cover of band explosion suppresion surface is equipped with on the top of housing by securing member, the heating tape lead-in wire is housed in the housing, and draw the bottom of heating tape line outlet in the middle of main line outlet.
Described connection bolt is 6, is installed in the housing by the insulation fixed head, and adopts low arrangement of three Senior Three to put.
Described mounting panel is provided with built-in heating tape binding post.
The big capacity explosion-proof motor of the low pressure terminal box of making according to such scheme, adopt 6 connection bolts to connect the structure of 12 lead-in wire binding posts, thereby reduced the cross-sectional area of motor down-lead, and guaranteed electric clearance and creepage distance in the terminal box preferably, make the structure of terminal box inside compact more simultaneously, overall volume is dwindled greatly, has strengthened the harmony of terminal box and electric machine stand.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of connection bolt;
Fig. 4 is the cutaway view of P-P among Fig. 2.
Embodiment
Referring to Fig. 1, Fig. 2, the big capacity explosion-proof motor of low pressure of the present utility model terminal box, comprise housing 1 and connector cover 3, wherein, the bottom of housing 1 is provided with the through hole that is used to install lead wire, the position corresponding with this through hole is connected with a mounting panel 5, and be connected with electric machine stand by mounting panel 5. be provided with insulation fixed head 6 in the housing 1, be coated with 6 on it and adopt the low M24 connection bolt 2 that is misplaced mutually of three Senior Three, the lower end of each connection bolt 2 has 2 binding post 2-1 (see figure 3)s, 12 motor leads pass mounting panel 5 and the corresponding connection of binding post 2-1 on the connection bolt 2. built-in heating tape binding post 4 is housed on the mounting panel 5, one side of housing 1 is provided with 2 and has the wiring wire hole 7 of explosion separation structure and heating tape wiring wire hole 8 (see figure 4)s that 1 has explosion separation structure, and be triangularly arranged, being respectively applied for and installing motor power wiring and heating tape power supply wiring. this connection box for motor is owing to adopted 6 connection bolts to be connected the structure of 12 binding post 2-1 that go between, reduced the cross-sectional area of motor down-lead greatly, made the cross-sectional area of every lead-in wire narrow down to 95mm
2, far below general lead-in wire cross-sectional area 120mm
2Conventional permissible value, guaranteed electric clearance and creepage distance in the terminal box preferably, heating tape wiring simultaneously is arranged in the terminal box, makes the structure of terminal box inside compact more, overall volume is dwindled greatly, strengthened the harmony of terminal box and electric machine stand.
