Description
Technical field
The utility model relates to electrical equipment, particularly relates to a kind of distribution box.
Background technology
A total circuit distributor box of user power utilization.Switchgear, measuring instrument, protective device and auxiliary equipment are assembled in closed or semiclosed metal safe by electrical wiring requirement or on screen width, form power distribution equipment by distribution box.Can connect or point deenergizing by manual or automatic switch during normal operation.Circuit or warning is cut off by protective device when fault or irregular operating.Operating various parameter can be shown by means of measuring instrument, also can adjust some electric parameter, point out departing from normal operating conditions or send signal.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 applied in the market usually; 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, leaks electricity once contact with electric component; casing will be charged; when staff open distribution box carry out Installation and Debugging operation time, just may there is electric leakage accident, threaten to the safety of staff.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of electric leakage from fusing distribution box, one is provided with by the relay of case control and fuse in this distribution box, when occurring that electric leakage makes casing charged, normally opened relay closes, and fuse wire, ensure that the life security of staff.
The utility model is achieved in that a kind of electric leakage is from fusing distribution box, comprise casing, described casing is built with fuse holder, fuse on described fuse holder is connected on the backbone of electric wiring, normally opened relay and protection power supply is also provided with in this distribution box, normally opened relay is in parallel with fuse with after protection power sources in series, and the control joint of described normally opened relay is communicated with on casing by wire.
The front of described casing is provided with installation cover plate, and described installation cover plate is connected with casing by bearing pin.
Described casing is seal case, is provided with sealing rubber ring between described installation cover plate and casing.
Described installation cover plate is equipped with transparent window.
The utility model electric leakage is provided with a fuse on the backbone of the inherent electric wiring of fusing distribution box, and be additionally provided with a protection power sources in parallel on fuse, protection circuit is connected a normally opened relay, when occurring that electric leakage makes casing charged, normally opened relay closes, fuse wire, ensure that the life security of staff.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of the utility model electric leakage from fusing distribution box;
Fig. 2 is the appearance schematic diagram of the utility model electric leakage from fusing distribution box.
In figure: 1 casing, 2 installs cover plate, 3 fuse holders, 4 fuses, 5 normally opened relays, 6 protection power supply, 7 bearing pins, 8 sealing rubber rings, 9 transparent windows.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model statement.
Embodiment 1
As Fig. 1, shown in 2, a kind of electric leakage is from fusing distribution box, comprise casing 1, described casing 1 is built with fuse holder 3, fuse 4 on described fuse holder 3 is connected on the backbone of electric wiring, normally opened relay 5 and protection power supply 6 is also provided with in this distribution box, normally opened relay 5 is in parallel with fuse 4 after connecting with protection power supply 6, the control joint of described normally opened relay 5 is communicated with on casing 1 by wire, when distribution box leakproof, the contact of normally opened relay 5 disconnects, on fuse 4 without any impact, when distribution box electric leakage makes casing 1 charged, solenoid in normally opened relay 5 obtains the electric control closing of contact, make protection power supply 6 directly and fuse 4 conducting form short circuit, fuse wire, the overall power-off of such distribution box, drain conditions can not there is, ensure that the life security of staff.
The utility model front that can further describe as, described casing 1 is provided with installs cover plate 2, and in order to switch is convenient, the installation cover plate 2 in the utility model is connected with casing 1 by bearing pin 7; Consider the closure of distribution box, described casing 1 is seal case, is provided with sealing rubber ring 8 between described installation cover plate 2 and casing 1, to ensure the sealing effect of casing 1.In addition, transparent window 9 is equipped with in order to the reading of instrument in distribution box can be observed easily, described installation cover plate 2.
