Description
Technical field
The utility model relates to electric equipment field, relates in particular to a kind of distribution box.
Background technology
A total circuit distributor box of user power utilization.Distribution box is assembled in sealing or semiclosed metal safe by switchgear, measuring instrument, protective device and auxiliary equipment or shields on width by electrical wiring requirement, forms power distribution equipment.When normal operation, can connect or point deenergizing by manual or automatic switch.When fault or irregular operating, cut off circuit or warning by protective device.Borrow measuring instrument can show operating various parameter, also can adjust some electric parameter, point out or send signal to departing from normal operating conditions.Be usually used in each, join, in electric substation.
The support of all kinds equipment can be set in the casing of the distribution box of application in the market conventionally; such as circuit breaker, detecting instrument etc.; these supports are all fixedly linked with screw and casing; screw is generally metal conductive materials; exposed at box house, once contact and leak electricity with electric component, when opening distribution box, staff carries out Installation and Debugging whens operation; just may there is electric leakage accident, threaten to staff's safety.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of earth leakage protective distribution box; the connecting bolt of the electric component support in this distribution box arranges a conductive spacer; and by all conductive spacer ground connection; even if bolt contact electric leakage also can not cause danger to staff like this, improve the safety and reliability of distribution box.
The utility model is achieved in that a kind of earth leakage protective distribution box; comprise the casing of sealing; the front of described casing is for installing cover plate; in described casing, be provided with electric component support; described electric component support is mounted by means of bolts in casing; on bolt, be set with pad, described pad is made up of electric conducting material, and pad is communicated with earth connection by wire.
After all described wire parallel connections, be communicated with earth connection.
Described installation cover plate is connected with casing by bearing pin, installs between cover plate and casing and is provided with sealing rubber ring.
On described installation cover plate, transparent window is housed.
Described electric component support comprises circuit breaker cradle, measuring instrument support, contact mount.
The connecting bolt of the electric component support in the utility model earth leakage protective distribution box arranges a conductive spacer; and by all conductive spacer ground connection; even if bolt contact electric leakage also can not cause danger to staff like this, improve the safety and reliability of distribution box.
Brief description of the drawings

In figure: 1 casing, 2 is installed cover plate, 3 electric component supports, 4 bolts, 5 bearing pins, 6 sealing rubber rings, 7 transparent windows, 8 pads, 9 wires.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, 2, a kind of earth leakage protective distribution box, comprise the casing 1 of sealing, the front of described casing 1 is for installing cover plate 2, in described casing 1, be provided with electric component support 3, in the present embodiment, described electric component support 3 comprises circuit breaker cradle, measuring instrument support, contact mount and other the electric component supports that may use; Described electric component support 3 is fixedly mounted in casing 1 by bolt 4, on bolt 4, be set with pad 8, described pad 8 is made up of electric conducting material, pad 8 is communicated with earth connection by wire 9, even if bolt 4 comes in contact electric leakage with electric component like this, electric current also can lead to earth connection from pad 8, can not produce infringement to human body.
In the present embodiment; have influence on overall safeguard protection for fear of some pad 8 imperfect earths; after all described wire 9 is in parallel, is communicated with earth connection, any one pad 8 opens circuit and does not also have influence on the ground path of other pads like this, has improved the protection reliability of this distribution box.
Convenient for switch, the installation cover plate 2 in the utility model is connected with casing 1 by bearing pin 5, installs between cover plate 2 and casing 1 and is provided with sealing rubber ring 6, to ensure the sealing effect of casing 1; In addition, in order to observe easily the reading of instrument in distribution box, on described installation cover plate 2, transparent window 7 is housed.
