Description
Technical field
The utility model is related to field of generating equipment, especially a kind of small-sized afterheat generating system control device.
Background technology
Along with the proposition of the idea one by one such as sustainable development, circular economy, energy-saving and emission-reduction and low-carbon economy, China
Cogeneration industry experienced development course from scratch, from small to large.Electrical equipment configuration one in traditional thermoelectricity system
As it is as follows：Generator connecting in parallel with system cabinet, generator back protection screen (protection equipment for generator, power generation line protective devices), are adjusted PT cabinets
Speed variator, same period cabinet, DC power supply, excitation cubicle etc..Thermoelectricity has developed many decades at home, and to this, electrical configuration has become mark
It is accurate.Thus in emerging cogeneration project, many projects are designed also according to the electrical configurations of previous big thermoelectricity, apply
Work.But the generator that small-sized cogeneration uses is different, the synchronous generator of big thermoelectricity, and small-sized cogeneration project
In, it is more selection asynchronous generator, then in small-sized cogeneration project if while selecting asynchronous generator, still
Following defect is there is when so according to the electrical configurations of thermoelectricity：System complex involves great expense；Generator is complicated, high failure rate；It is right
It safeguards and maintenance personal requires height；Electrical back protector requirement is high, the wasting of resources.
In small-sized cogeneration project, generator selects asynchronous generator, due to inside asynchronous generator without excitation around
Group or exciting current can establish air-gap field, therefore, such as run as generator, need an external power supply supply generator
Reactive current is used as excitation, therefore Induction generation system does not just have to dedicated excitation unit, therefore does not need to configuration excitation cubicle, and excitation is come
From plant area's power grid, while asynchronous generator can not also generate reactive power.Since generator is grid-connected very simple without excitation event in itself
It is single, prime mover dragging asynchronous generator is only needed to be promoted to rotating speed grid-connected after rated speed, therefore do not need to be configured dedicated
Same period cabinet due to not needing to synchronous device, therefore does not need to measure generator outlet voltage signal, therefore can cancel generator outlet again
PT cabinets.Since the excitation of generator is from plant area's busbar, therefore generator frequency and voltage are consistent with plant area busbar, so not needing to
Special arrangements for speed regulation (synchronous generator speed determines generator frequency), so the electrical configurations after simplification are as follows：It is grid-connected
Cabinet (built-in grid-connected breaker, multifunctional meter, ct, generator back protection protective device etc.)；PT cabinets are (because of cogeneration project all
It is not grassroot project, therefore there are spare pt signals on general busbar, this pt signal is protected after being used for generator and metering is used.It is because female
Line voltage is consistent with generator voltage.So when such as former busbar can provide PT signals.This cabinet can be cancelled).This mode it is excellent
Gesture is as follows：Cabinet is few；Low cost, maintenance cost are low；High-voltage board there are one only, floor space are small；Dedicated DEH is not needed to adjust
System, low cost.
At present, the high-voltage board that small-sized afterheat generating system uses for traditional structure high-voltage board, including cabinet, inside cabinet
A plurality of cavities are separated into, multiple electrical equipments are installed in each cavity, since the size of cavity is limited, the installation of electrical equipment
It is inconvenient.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of small-sized afterheat generating system control devices, change it
The structure of high-voltage board, the installation of more convenient electrical equipment.
Technical solution is used by the utility model solves its technical problem：A kind of small-sized afterheat generating system control dress
Put, including high-voltage board, the high-voltage board includes cabinet, and the cabinet is provided with cavity, the cavity by polylith level support
Plate and the vertical partition board of polylith are separated into multiple installation cavitys, and two pairs of vertical studs, each pair of spiral shell are provided in each installation cavity
The guide rail of multiple levels, the guide rail and stud clearance fit are provided on column, and is provided on the stud below each guide rail
Holding nut；Guide rail quantity on two pairs of studs is equal and vertical position corresponds；The side of the guide rail is provided with sliding slot,
Horizontal installing plate is provided on two pairs of studs between corresponding two guide rail, the two sides of the installing plate are located in sliding slot simultaneously
It is slidably matched with guide rail.
Further, the upper surface of the guide rail is provided with threaded hole, and housing screw is provided in the threaded hole, described
The lower end of housing screw compresses installing plate.
The beneficial effects of the utility model are：When installing electrical equipment, installing plate is taken out, electrical equipment is mounted on peace
In loading board, then guide rail is adjusted to suitable height by rotating holding nut, installing plate is finally inserted into the sliding slot of guide rail
.It since electrical equipment can be installed outside cabinet cavity, is not restricted by space size, easier for installation quick, energy
Construction efficiency is enough improved, and is overhauled also more convenient.
