Description
Technical field
The utility model relates to a kind of switch-box, particularly relates to a kind of residential building head switch-box, belongs to electric equipment products field.
Background technology
At present, even tens buildings that some some buildings of low-pressure line-outgoing band, old residential quarter one road have power, and lack separately to the switch-box that each building controls, when a building power supply facilities goes wrong, cause other buildings also to have a power failure, occur that power supply reliability is poor, large-area power-cuts phenomenon.
Utility model content
The purpose of this utility model is to provide a kind of residential building head switch-box; integrate electric leakage, overcurrent, open-phase protection and runback Electricity Functional; for the building head of old community; as total protection in this building; large-area power-cuts phenomenon can be greatly reduced; improve power supply reliability, promote company's good service level.
Residential building head switch-box described in the utility model, comprise casing, the side of casing is provided with chamber door, is provided with mounting panel in casing, and mounting panel is equipped with residual current circuit breaker, the both sides up and down of residual current circuit breaker connect copper bar, be equipped with low pressure post insulator between each copper bar and casing, copper bar has good conductivity, is widely used on controller switching equipment, low pressure post insulator is a kind of special insulation control, can play an important role in overhead transmission line.
Described residual current circuit breaker comprises disconnect, release, electronic building brick wiring board, open-phase protection circuit, zero sequence current mutual inductor and automatic reclosecontroller; disconnect connects release, electronic building brick wiring board, open-phase protection circuit, zero sequence current mutual inductor and automatic reclosecontroller respectively, has electric leakage, overcurrent, open-phase protection and runback Electricity Functional.
Casing adopts stainless steel, has surface aesthetic, good corrosion resistance, can prevent from getting rusty, safeguarding simple advantage.
The utility model compared with prior art, has following beneficial effect:
A kind of residential building head switch-box is provided; integrate electric leakage, overcurrent, open-phase protection and runback Electricity Functional; for the building head of old community, as total protection in this building, make each building separately protected; large-area power-cuts phenomenon can be greatly reduced; improve power supply reliability, tank surface is attractive in appearance simultaneously, and the life-span is long; can prevent from getting rusty, safeguarding simply, effectively can promote company's good service level.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is residual current circuit breaker enlarged diagram;
In figure: 1, casing 2, mounting panel 3, low pressure post insulator 4, residual current circuit breaker 5, chamber door 6, copper bar 7, disconnect 8, release 9, automatic reclosecontroller 10, electronic building brick wiring board 11, open-phase protection circuit 12, zero sequence current mutual inductor.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
As shown in Figure 1, residential building head switch-box described in the utility model, comprise casing 1 and chamber door 5, mounting panel 2 is provided with in casing 1, residual current circuit breaker 4 mounting panel 2 is equipped with, the both sides up and down of residual current circuit breaker 4 connect copper bar 6, and be equipped with low pressure post insulator 3 between each copper bar 6 and casing 1, casing 1 adopts stainless steel.
As shown in Figure 2; residual current circuit breaker 4 comprises disconnect 7, release 8, electronic building brick wiring board 10, open-phase protection circuit 11, zero sequence current mutual inductor 12 and automatic reclosecontroller 9, and disconnect 7 connects release 8, electronic building brick wiring board 10, open-phase protection circuit 11, zero sequence current mutual inductor 12 and automatic reclosecontroller 9 respectively.
Embodiment
As preferably, for three-phase and four-line electricity, open chamber door 5, residual current circuit breaker 4 is provided with in casing, the upper end of residual current circuit breaker 4 connects 4 pieces of copper busbars 6, the lower end of leak electricity short-circuit device 4 connects 4 pieces of copper busbars 6, copper busbar 6 has good conductivity, be widely used on controller switching equipment, low pressure post insulator 3 is equipped with between each copper bar 6 and casing 1, totally 8 low pressure post insulators 3, low pressure post insulator 3 is a kind of special insulation controls, can play an important role in overhead transmission line, the electric situation of the company of avoiding occurs, residual current circuit breaker 4 comprises disconnect 7, release 8, electronic building brick wiring board 10, open-phase protection circuit 11, zero sequence current mutual inductor 12 and automatic reclosecontroller 9, disconnect 7 connects release 8 respectively, electronic building brick wiring board 10, open-phase protection circuit 11, zero sequence current mutual inductor 12 and automatic reclosecontroller 9.When electric leakage in protected circuit or the person get an electric shock, the secondary winding of zero sequence current mutual inductor 12 just exports a signal, and make disconnect 7 action by release 8, thus cut off the electricity supply play electric leakage and electrical shock protection effect, when in circuit, electric current is excessive, through electronic building brick wiring board 10, the signal voltage responded to by zero sequence current mutual inductor 12 differentiates that amplification drives release 8, thus disconnect 7 disconnects, cut off the electricity supply and protect, when there is phase shortage in circuit, zero sequence current mutual inductor 12 detects that signal transmission is to open-phase protection circuit 11 and electronic building brick wiring board 10, after to signal transacting, by signal transmission to release 8, determine the closed protective effect played circuit of disconnect 7.When after trouble shooting, utilize mechanical automation principle, in conjunction with automatic reclosecontroller 9, can solve because of transient fault cause switch trip to have a power failure after can not the problem of automatic recovery of power supply, realize runback Electricity Functional.
Adopt the residential building head switch-box of the above preferred embodiment of the present utility model described by reference to the accompanying drawings, achieve electric leakage, overcurrent, open-phase protection and runback Electricity Functional, but the utility model is not limited to described execution mode.
