Abstract
The utility model discloses a kind of cooling control cabinet, comprise casing and top cover, it is characterized in that: be provided with PLC, frequency converter, circuit breaker, heater and zero line copper bar in casing, described zero line copper installation is in the both sides of box house, and bottom half is provided with ventilating opening and incoming line; Heater is positioned at the bottom of casing, and cooling fan, rainproof layer, thermal insulation layer and ventilating opening are positioned at casing top; The frequency converter of lengthwise is vertically arranged at top in casing and close side zero line copper bar; PLC, Switching Power Supply and temperature detect switch (TDS) are positioned at the frequency converter side of lengthwise and are close to opposite side zero line copper bar; Circuit breaker and service entrance switch are positioned at below frequency converter also near incoming line; The cooling that the utility model is applicable to the oil-immersed type transformer that electric power system 220kV and above adopt forced oil-circulation air-cooled controls.
Description
Technical field
The utility model belongs to the energy-conservation device of transformer station, relates generally to a kind of cooling control cabinet.
Background technology
One of measure that transformer station is energy-conservation, adopts main transformer cooler frequency conversion control technique, consumes energy for reducing main transformer cooler high-power blower.In recent years, the control cubicle cooling how realizing the industry spot such as electric cabinet, rack, electrical control cubicles is a large problem with refrigeration radiating, opens cabinet door in prior art, blows and install the cooling measures such as cabinet air conditioner to have a lot of weak points with fan.
Utility model content
Utility model object: the utility model provides a kind of energy-saving cooling control cabinet being applicable to electric power system 220kV and above main transformer.
Technical scheme: a kind of cooling control cabinet, comprises casing and top cover, is provided with PLC, frequency converter, circuit breaker, heater and zero line copper bar in casing, and described zero line copper installation is in the both sides of box house, and bottom half is provided with ventilating opening and incoming line; Heater is positioned at the bottom of casing, and cooling fan, rainproof layer, thermal insulation layer and ventilating opening are positioned at casing top; The frequency converter of lengthwise is vertically arranged at top in casing and close side zero line copper bar; PLC, Switching Power Supply and temperature detect switch (TDS) are positioned at the frequency converter side of lengthwise and are close to opposite side zero line copper bar; Circuit breaker and service entrance switch are positioned at below frequency converter also near incoming line.
Further, Switching Power Supply is provided with below described PLC.
Further, service entrance switch is provided with below described circuit breaker.
Further, described casing is front and back opening door, and front/rear door is equipped with air intake dust board.
Further, described in be provided with across the control board in casing both sides, control board is arranged some control buttons.
Beneficial effect: a kind of cooling control cabinet that the utility model provides, the cooling being applicable to the oil-immersed type transformer that electric power system 220kV and above adopt forced oil-circulation air-cooled controls.Wherein, by heater and cooling fan and thermal insulation layer as far as possible away from, heater is positioned at low side, and cooling fan and thermal insulation layer are positioned at casing top.When temperature is lower need heater be heated to inner member start time require temperature time, the heat that heater can be made to provide is full of in whole casing from bottom to top, and raise when working temperature after starting and need cooling fan to lower the temperature, heater and cooling fan and thermal insulation layer are away from the error starting of cooling fan when also can not cause heating.
Further, the frequency converter of lengthwise is vertically arranged and PLC and temperature detect switch (TDS) are positioned at by frequency converter, make the layout of inner member compacter, the space in less waste casing, be conducive to the miniaturization of casing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front view of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
As shown in Figure 1-2, a kind of cooling control cabinet, comprises casing 1 and top cover 2, is provided with PLC 5, frequency converter 6, circuit breaker 9, heater 3 and zero line copper bar 4 in casing, zero line copper bar 4 is arranged on the both sides of casing 1 inside, and bottom half is provided with ventilating opening 13 and incoming line 12; Heater 3 is positioned at casing 1 bottom, and cooling fan (not shown), rainproof layer, thermal insulation layer and ventilating opening 13 are positioned at casing 1 top; The frequency converter 6 of lengthwise is vertically arranged at top in casing 1 and close side zero line copper bar 4; PLC 5 and temperature detect switch (TDS) 8 are positioned at frequency converter 6 side of lengthwise and are close to opposite side zero line copper bar 4; Switching Power Supply 7 is provided with below PLC 5; Circuit breaker 9 to be positioned at below frequency converter 6 and near incoming line 12, to be provided with service entrance switch 11 below circuit breaker 9; Casing 1 is front and back opening door, and front/rear door is equipped with air intake dust board; Also be provided with across the control board in casing 1 both sides, control board arranged some control buttons 10.
The cooling machine cabinet blower fan filled in casing 1, is mainly used to reduce casing 1 interior environment temperature; The form that casing 1 opens the door for front and back, sunshade thermal insulation layer and rainproof layer are arranged at top, are ventilating opening 13 below it.The bottom of casing 1 is incoming line 12 and ventilating opening 13.The front/rear door of casing 1 has air intake dust board.The characteristic that it has rain and snow invasion, invasions etc. that are sun-proof and other extraneous solids are suitable for outdoor use.
The energy-saving cooling control cabinet topology layout that the utility model is applicable to 220kV and above main transformer is comparatively compact, easy for installation, debugging is simple, can be used for three-phase alternating current 50 hertz, rated voltage 0.38-0.66 kilovolt, transformer voltage grade is that the main transformer oil of more than 220 kilovolt-amperes controls, and the cooling for the large-scale main transformer of more than the 220kV using forced oil-circulation air-cooled controls, and uses ideal.
