Abstract
The utility model discloses a novel distribution box for construction site, comprising an inlet wire holder (1), a common substrate grounding wire holder (2) and a device socket A (3), wherein the inlet wire holder of the distribution box is connected with the U, V and W phase wires and a neutral wire N, and the device socket (3) is connected with a leakage protector A (6), a screw type fuse cutout A (11), a screw type fuse cutout B (12) and a screw type fuse cutout C (13). Since each protection wire needed to be grounded is corresponding to a wire holder, and an erroneous wire or missed wire can be seen easily, easy for operators and safety check worker to determine the line status. After the screw type fuse cutouts are connected, when the leakage protector executes the leakage protection action, a maintenance worker unscrews the caps of the screw type fuse cutouts, so that the line is disconnected easily, avoiding the possibility of electric shock.
Description
Technical field
The utility model relates to a kind of distribution box, relates in particular to the novel distribution box that a kind of construction site uses.
Background technology
What used in the construction site at present is the used distribution box of 380/220V three phase and four wire circuit system; owing to be not provided with separately for the shared ground connection junction block of multiple devices ground connection; the more weak operator of some labor safety consciousness tends to occur some mistakes; is that N directly joins with the zero connection protection line of the metal shell of construction equipment with the power supply neutral line; in the electric loading imbalance; when producing zero-sequence current, earth connection produces voltage to earth, and electric shock accidents takes place.The earth connection of multiple devices is connected on a certain on the earthing of casing screw of grounding apparatus.Such result makes the end of a thread twine in a jumble, and operator and security staff can not clearly distinguish wire connection state.A plurality of the end of a thread also are difficult for stable on a ground connection screw, easily cause virtual connection, misconnection phenomenon.
Summary of the invention
According to above technical problem; the utility model proposes the novel distribution box that a kind of construction site uses; by inlet wire junction block (1); cobasis plate earthing junction block (2); apparatus socket A (3); apparatus socket B (4); apparatus socket C (5); earth leakage protective device A (6); earth leakage protective device B (7); earth leakage protective device C (8); earth leakage protective device D (9); apparatus socket D (10); screw type fuse A (11); screw type fuse B (12); screw type fuse C (13); wiring mounting panel (14); form; the inlet wire junction block and the U that it is characterized in that distribution box; V; three phase lines of W are connected with neutral line N; apparatus socket A (3) and earth leakage protective device A (6); screw type fuse A (11); screw type fuse B (12); screw type fuse C (13) links to each other; apparatus socket B (4) and earth leakage protective device B (7); screw type fuse A (11); screw type fuse B (12); screw type fuse C (13) links to each other; apparatus socket C (5) and earth leakage protective device C (8); screw type fuse A (11); screw type fuse B (12); screw type fuse C (13) links to each other, and apparatus socket D (10) substrate ground connection junction block (2) together links to each other with earth leakage protective device D (9).
The utility model beneficial effect is: the utility model is the distribution box that use a kind of job site with independent grounding junction block, and make line alignment distinct, can make operator and security staff when checking circuit, understand circuit at a glance, determine whether safety of electronic box.The common metal substrate ground connection junction block with two above binding posts that is provided with is screwed in the protection connecting to neutral line of each equipment respectively on each binding post separately, and ground connection is firm, contact resistance is little, no virtual connection phenomenon; Because every needs the protective wire of ground connection all to sit in the right seat on junction block; wrong line or few wiring a glance just can be found out; easy operating person and security staff differentiate line conditions; after inserting screw type fuse; when earth leakage protective device is carried out the earth leakage protective operational motion; the molten cap that the maintainer is revolved plug fuse is open-circuit line significantly just, has avoided the possibility of getting an electric shock.
