Abstract
The utility model discloses a kind of Portable power box; comprise casing; casing both sides are provided with into electrical interface and power transmission interface; inside is provided with total power switch; power transmission interface all arranges an earth leakage circuit-breaker in box house correspondence; controlled by total power switch after earth leakage circuit-breaker parallel connection, when one of them leakage switch goes wrong, the normal work of other leakage switch can not be affected.The efficiency of site construction is improve under the prerequisite of safety guarantee.
Description
Technical field
The utility model relates to a kind of mobile controller switching equipment, particularly relates to a kind of Portable power box carrying out powering at the construction field (site).
Background technology
Engineering construction is on-the-spot, and in work progress, often will use multiple power consumption equipment, these power consumption equipments provide the supply of power supply usually by the power supply box of job site simultaneously.At present, job site mainly adopts portable power source drum to power to power consumption equipment, and it, by comprising support and rack-mount rotating rotating disk, rotating disk coils service cable, and the side of rotating disk then arranges multiple supply socket.It connects power supply at a distance by cable, then by the multiple supply sockets on rotating disk, realizes powering to multiple power consumption equipments of job site simultaneously.But power wire coil, exists following shortcoming: 1, its volume and weight are large, are not easy to carry, cable and bracing frame and rotating disk one, transport also cumbersome, inconvenience.2, it only arranges a leakage switch usually, controls multiple supply socket by a leakage switch simultaneously, and when the equipment on the circuit that one of them supply socket is powered goes wrong, the equipment that several supply socket is powered all will be affected, and bring inconvenience.3, water proofing property is bad, easily causes Electrical Safety accident.4, fragile in use procedure, easily trip, maintenance cost is large.
Summary of the invention
The purpose of this utility model is to provide a kind of easy to use, small volume and the higher Portable power box of security performance.
A kind of Portable power box described in the utility model, comprises casing and chamber door, arranges sealing gasket between casing and chamber door, box house can be sealed when chamber door closes on casing; Arrange the waterproof power-line plug of plant-grid connection in the side of casing, the opposite side of casing arranges multiple waterproof power line socket of being drawn by power supply; In casing, the waterproof power-line plug of plant-grid connection is connected total supply line, and total supply line is further divided into multiple points of supply lines, and Ge Fen supply line is electrically connected with each waterproof power line socket of being drawn by power supply respectively; In casing, be provided with total earth leakage circuit-breaker and multiple points of earth leakage circuit-breakers, total leakage switch is arranged in total supply line, and each point of earth leakage circuit-breaker is then arranged in Ge Fen supply line respectively.
The new described Portable power box of this practicality, during use, what arranged casing side connects service cable by the waterproof power-line plug of plant-grid connection, the waterproof power line socket that power supply is drawn is got final product supplying power for outside by the multiple of casing opposite side, by using the waterproof power line socket docking coordinated with it, power supply can be drawn and power to construction equipment, easily must achieve multiple-way supply, can power to multiple construction equipment simultaneously.Its supply lines separates with power supply box, lightweight, and volume is little, transhipment and very convenient to carry.And described compact power box structure is also comparatively simple, and cost is also lower; And the use of Portable power box can reduce the layout of on-the-spot three stage power source case, reduce while guarantee security performance and face electric integral material cost.Meanwhile, point power supply circuits that its waterproof power-line plug of respectively being drawn by power supply is corresponding are provided with independent earth leakage circuit-breaker, each earth leakage circuit-breaker can when respective supply line occurs abnormal power-off protection.One Ge Fen supply line is abnormal, can not have influence on the work of other point of supply line.Well avoid job site because of a line facility generation exception, and affect the problem of the use of other construction equipment.In addition, described Portable power box all adopts water joint, and water resistance is good, safe and reliable.
Described casing can arrange handle, lift to be more convenient for, carry.Can coated one deck spiral type insulating sleeve at the outer of handle, while improving security performance further, can also improve and grasp to obtain comfortableness, and can be anti-skidding.

Embodiment
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of Portable power box, the handle 20 comprising a casing 10 and be arranged on casing 10, casing adopts Q235 carbon steel material to make, thickness is 0.75mm, specification is 300*220*100mm, and surface and inner side grey paint preservative treatment, handle 20 outer cladding spiral type insulating sleeve, chamber door 11 is set on front side of casing 10, chamber door 11 is provided with snap close 111, in usual situation, chamber door closes, snap close is locked, by box sealing, when breaking down in inside, convenient maintenance can be opened.Casing 10 side is provided with the waterproof power-line plug 12 of plant-grid connection as entering electrical interface, the another side of casing is provided with two waterproof power line sockets 13 of being drawn by power supply as power transmission interface, enter electrical interface and power transmission interface and all select blue waterproof socket in concealed installation, IP68, operating current 16A, line 2P+E, male end and female end joint, as shown in Figure 3, power transmission interface selects concealed installation straight cutting seat, enters electrical interface and selects concealed installation straight inserting head.Connect total supply line entering electric connection, total supply line is further divided into multiple points of supply lines, and Ge Fen supply line is electrically connected with each waterproof power line socket (power transmission interface) of being drawn by power supply respectively; In casing, be provided with total earth leakage circuit-breaker 15 and multiple points of earth leakage circuit-breakers 14, total leakage switch is arranged in total supply line, and each point of earth leakage circuit-breaker is then arranged in Ge Fen supply line respectively.Earth leakage circuit-breaker 14 correspondence controls the electricity consumption of a user, decreases and causes the affected situation of other users because of a user power utilization problem, reduces circuit trip phenomenon.When it is desired to be used; assembling mode is adopted to be connected with the joint of inlet wire cable the electrical interface that enters of power supply box; inlet wire cable size is 3*1.5; after connecting 220V power supply, connect total power switch 15 and earth leakage circuit-breaker 14, just start working; when circuit goes wrong; corresponding earth leakage circuit-breaker 14 disconnects, and does not affect the electricity consumption supply of other circuit, improves the efficiency of construction on building site.
