Description
Technical field
The present invention relates to the assembly of low-voltage complete switch equipment, relate in particular to a kind of pluggable secondary control system assembly.
Background technology
At present the type of the more low-voltage complete switch equipment used of China market mainly contains following three kinds: fixed sealing enclosed, pull-out type, fixing cellular-type.
Fixed sealing enclosed low-voltage complete switch equipment is owing to reasons such as single, the general interchangeability of structure is strong, user's maintenance, replacing element inconvenience progressively are eliminated.Now main product is pull-out type and fixing cellular-type low-voltage complete switch equipment, also there is following defective in these two kinds of products: at first, primary element and secondary component in the functional unit of pull-out type low-voltage complete switch equipment are mounted in the same drawer, this draw-out type functional units can break away from cabinet, advantage is can make things convenient in process of production, produce in enormous quantities quickly, and the user is easy to maintenance, safety, shortcoming is that the primary circuit of this draw-out type functional units is communicated with major loop by a plug, in the phenomenon that burns out through regular meeting plug position of appearance in service of switching on for a long time, cause great potential safety hazard and economic loss for electricity consumption to the user; Secondly, fixedly the functional unit of cellular-type low-voltage complete switch equipment is with plug-type switch fixed installation, have and contact reliable, disjunction making capacity advantages of higher, but secondary control system is to be fixed on fixedly in the separating element as control relay element etc., so just cause that production efficiency is low, the user safeguards shortcomings such as inconvenience, if secondary component is because of damaging or control system function upgrading when needing replacing, primary system must cut off the power supply, cause power consumption equipment to have a power failure, influence user's ordinary production.
The secondary circuit Connection Step of existing fixedly cellular-type low-voltage complete switch equipment separation function unit is as follows: at first cabinet is installed, primary element is installed then, secondary component is installed again, last wiring.Because fixedly the space of cellular-type low-voltage complete switch equipment separation function unit is limited, be generally wide 600mm, high 200mm at present, or wide 600mm, high 400mm, or wide 600mm, high 600mm.Because the space of separation function unit is limited, and need operate in cabinet, bring great inconvenience so just for factory's wiring worker wiring, have a strong impact on production efficiency.Secondary line connection at present is to connect with common fixedly connected terminal in addition, need fixedly in the separation function unit terminal frame and secondary component installing rack be set, so just cause inside, separation function unit more in disorder, not attractive in appearance, the more important thing is inconvenient maintenance in the future, the onsite user is overhauled, can not convenient and swiftly operate when changing element, and in case the situation that element is damaged and need changes in the separation function unit is arranged, just can operate after need be in cabinet the major loop switch being broken, at this moment other separation function unit in the cabinet still is in normal charging operation state, operate in cabinet and be absolutely unsafe this moment, do not have safety guarantee.
Summary of the invention
Problem to be solved by this invention is: a kind of pluggable secondary control system assembly is provided, can guarantee the user when control system is damaged or is needed function upgrading safety, change easily and do not influence power supply.
The object of the present invention is achieved like this: a kind of pluggable secondary control system assembly, comprise control loop element 16, plate 19, control loop master switch QF117, plug terminal 18, control loop master switch QF117, plug terminal 18, control loop element 16 are arranged on the plate 19, control loop master switch QF117 is connected with plug terminal 18, and control loop element 16 is connected with plug terminal 18.
A kind of fixedly cellular-type low-voltage complete switch equipment comprises cabinet 1, is arranged on main bus bar chamber, cable vault 8 in the cabinet 1; Also be provided with at least one separation function unit 4 in the cabinet 1, separation function unit 4 comprises primary circuit, unit assembly 20 and pluggable secondary control system assembly 7;
Primary circuit, unit assembly 20 comprises end of incoming cables branch bar 6, loop primary element mounting panel 9, loop primary element 10, leading-out terminal branch bar 11;
Pluggable secondary control system assembly 7 comprises control loop element 16, plate 19, control loop master switch QF117, plug terminal 18, and control loop master switch QF117, plug terminal 18, control loop element 16 are arranged on the plate 19; Control loop master switch QF117 one end is connected with plug terminal 18, and the other end is connected with end of incoming cables branch bar 6; Control loop element 16 is connected by plug terminal 18 with loop primary element 10;
Supply current flows into the outlet cabinet by main bus bar 2, insert separation function unit 4 through vertical bus 3, end of incoming cables branch bar 6, insert cable vaults 8 through leading-out terminal branch bar 11, pluggable secondary control system assembly 7 is arranged in the upper and lower slot 14,15 on separation function unit 4 sidewalls by insertion and is connected with primary circuit, unit assembly 20.
The invention has the advantages that:
1, in the process of producing product, cabinet do not assemble and primary element does not have arrival or situation about not being in place under, can on the operation element platform, carry out batch to pluggable secondary control system assembly earlier and assemble wiring, in cabinet and the primary element dress back that finishes pluggable secondary control system assembly is inserted corresponding separation function unit, finishing corresponding secondary line grafting gets final product, need wiring separately in cabinet, so just shortened the manufacturing cycle of product greatly;
2, in user's use,, the pluggable secondary control system unit replacement of identical function is once got final product, can not influence the normal operation of equipment if the pluggable secondary control system assembly in the separation function unit that has damages;
3, product puts into operation in the process or after the operation for many years, when the user wants product carried out function upgrading or change pluggable secondary control system assembly, can turn off control loop master switch QF1 earlier, pull up pluggable secondary control system assembly then, outside cabinet, pluggable secondary control system assembly is carried out replacement of element or renewal, so just can be under the situation of not cutting off the separation function unit load, pluggable secondary control system assembly is changed, or its controlled function is upgraded;
4, the present invention with the pull-out type low voltage switchgear and fixedly cellular-type low voltage switchgear advantage roll into one, have circuit breaker breaking capacity height, advantage that the equipment dynamic thermal stability is good, and because the secondary control system assembly is a plug type, therefore realize the flexible and changeable of secondary control system scheme, had combined and instant, practical, maintenance safe, characteristics easily.
