Description
Technical field
The utility model relates to flow battery field, particularly flow battery voltage polling field, is specifically related to flow battery voltage polling coupling arrangement.
Background technology
Modern economy social development, to the growing demand of traditional energy, makes the problem of its undersupply become increasingly conspicuous.People have to find the regenerative resource such as wind energy, sun power, the new forms of energy being representative with wind energy and sun power in recent years have occupied the one seat of energy resource supply, along with increase in demand, ratio is still in continuous increase, but it causes the intermittent imbalance between supply and demand of generating more outstanding by weather effect, the development of scale energy storage is imperative.
As the approach of extensive energy storage--the emergence and development of flow battery is that the defect of above-mentioned new forms of energy provides and well supplements.Flow battery has that security is good, the life-span is long; capacitance of storage is large, power is separated adjustable, addressing freedom with capacity and the feature such as clean environment firendly; the steady output of the new forms of energy such as wind energy, sun power after storing adjustment can be ensured, realize scale electric energy management, electrical network is assisted, the vital role of Control of Voltage, large-scale uninterrupted power source.
Flow cell pile is the place that chemical energy and electric energy transform mutually, and its structure is formed by stacking with pressure filter form for several monocells, and wherein, bipolar plates plays isolation both positive and negative polarity electrolytic solution and derives the effect of electronics in pile.Electrolytic solution due to flow battery has certain corrosivity, therefore cannot directly use metal as bipolar plate material.At present conventional bipolar plate material comprises: the materials such as graphite cake, charcoal plastic clad plate, above material because there is good corrosion resistance, the advantage such as intensity is high, electrical and thermal conductivity performance is excellent, liquid barrier property is good and being widely used in the pile of flow battery.
The voltage consistance of the inner monocell of pile is the key factor affecting flow cell pile and battery system overall performance.Therefore, for effectively understanding pile operation conditions, the inner single battery voltage of monitoring pile and pile global voltage situation, need to be equipped with suitable voltage polling device.Can say, utilize the accurate measurements of voltage polling device to each single battery voltage of pile be ensure the pile even prerequisite of flow battery general safety reliability service, and wherein voltage polling device with effective connection of monocell each in flow cell pile play a part key.
In prior art, the bipolar plate material of flow battery is by being become by hot pressing after the mixing of the raw material such as carbon black, cementing agent, due to the feature of itself material and structure, the mode of cannot directly to realize with the lead-in wire of inspection device by welding, riveting directly is fixed, its mode taked is generally processes patrol and examine connecting hole at the preparation bipolar plates initial stage outside it, the lead-in wire and bipolar plates of patrolling and examining voltage is fixed by this web member such as hole and bolt.But there are the following problems for current this mode:
1) bipolar plates by bolt with patrol and examine connecting hole with patrolling and examining to go between and be connected, patrol and examine between connecting hole due to bolt and bipolar plates and be difficult to form accurate dimensional fits, cause bolt and the contact of patrolling and examining between connecting hole may not be tight, and, along with battery system runs, patrol and examine the factors such as lead-in wire moves, bolt also can be patrolled and examined connecting hole with bipolar plates and constantly be rubbed, due to the feature of the material of bipolar plates own, the carbon granule of patrolling and examining hole wall easily comes off, anti-loosening and powerful pretightening technology cannot be adopted, and then greatly reduce the engagement capacity of patrolling and examining lead-in wire and bipolar plates, affect measuring accuracy,
2) due to after pile assembling, be limited to the thickness of electrode frame, two bipolar plates spacing is each other very little, less than 1 centimetre, therefore must will patrol and examine lead-in wire before pile assembling is connected in bipolar plates, and reduce the packaging efficiency of pile with many bipolar plates of patrolling and examining lead-in wire, and pile after assembling due to extra pin configuration can greatly increase its in transport, install and difficulty in moving process.
3) because the spacing between bipolar plates is too small, there will be at any time and patrol and examine wire wound, coupling bolt the situation touched in adjacent bipolar plates, thus cause short circuit between bipolar plates, affect the normal operation of pile.
4) when the situations such as inspection device damage, coupling bolt come off occur, bipolar plates can be deep into owing to there is no the instrument of suitable dimension to patrol and examine hole site and carry out keeping in repair or safeguarding, there is very large difficulty in the secondary maintenance therefore for inspection device, usual needs carry out disassembling pile work, find problem bipolar plates, patrol and examine after link changes to it, just can realize after carrying out a series of programs such as secondary assembling pile.Dismounting pile process wastes a large amount of manpower and materials and time, and secondary assembling process is also very easy to cause pile miscellaneous part to damage, and reduces pile quality.
CN101071867A proposes a kind of connected mode realizing patrolling and examining line and graphite cake, and the method utilizes drilling machine and mould after the side drilling of bipolar plates body goes out to patrol and examine wire machining hole, will patrol and examine wire be fixed in this machining hole to wear riveting mode.But the method needs special cross section boring bar tool, patrol and examine lead-in wire and only directly fix in thickness side, fixed effect is poor, patrols and examines line and is very easy to come off.
ZL201210436284.X and CN103151531A proposes a kind of connected mode realizing patrolling and examining line and sheet metal respectively, patrols and examines hole by directly being formed on metal bipolar plate thickness side, thus realizes patrolling and examining lead-in wire and be connected fast with the direct of bipolar plates.But the method is only only applicable to metal double polar plates, the processing of graphite cake or charcoal plastic clad plate cannot be realized, and patrol and examine hole and the fixed effect of patrolling and examining between lead-in wire is difficult to lastingly.
