Description
Technical field
The utility model relates to a kind of city rail safety protecting switch equipment, specifically a kind of portable type direct-current traction power supply switchgear.
Background technology
The supply power voltage of urban tram is generally direct current 750V, supply current is generally less than 2600A, current domestic main DC switch equipment is mainly for big current such as subways, heavy duty application scenario, for above-mentioned small area analysis, the urban track traffic DC traction system of low load, lack specially for the product of the low load of tramcar, the direct-current switch cabinet of tramcar design is not aimed at yet, normally continue to use the switchgear of existing large volume high cost, traditional wheelbarrow switch equipment, comprise cabinet and the handcart releasing cabinet can be advanced, handcart installs circuit breaker, requisite high pressure detecting element is all mounted on driver traditionally, thus on the one hand, add the volume of handcart, increase the weight of the weight of handcart, advance and release inconvenience, in addition on the one hand, the grafting part of the secondary component coordinated with cabinet in addition, reduce reliability of operation, in addition, existing switchgear, generally all there is handcart for subsequent use, handcart for subsequent use needs to have high pressure detecting element equally, cause the waste of cost.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of handcart is simple and compact for structure, volume is little, reliable, reduces the portable type direct-current traction power supply switchgear being widely used in the DC traction power-supply system of low load of operating cost.
In order to solve the problems of the technologies described above, portable type direct-current traction power supply switchgear of the present utility model, comprises cabinet and handcart, and cabinet is made up of breaker chamber, low-pressure chamber, bus-bar room, cable vault, hyperbaric chamber four part; Breaker chamber is arranged on the front lower portion of cabinet, and low-pressure chamber is arranged on the front upper part of cabinet, low pressure indoor location low voltage component and control protective unit; Bus-bar room and cable vault are arranged on the rear portion of cabinet, be provided with main busbar and a HV Terminal in bus-bar room, hyperbaric chamber is arranged on the upper back of cabinet, is provided with high pressure detecting element in hyperbaric chamber, form a handcart room below breaker chamber, handcart can push release handcart room.
In described bus-bar room, isolating switch is installed.
Described breaker chamber and low-pressure chamber are respectively arranged with independently room door.
The both sides inwall of described breaker chamber is provided with guide rail, and handcart both sides are provided with the guide support face coordinated with guide rail.
The front end of described guide rail is provided with and handcart can be made to be pushed into guiding surface in handcart room smoothly.
After adopting above-mentioned structure, because cabinet is made up of breaker chamber, low-pressure chamber, bus-bar room, cable vault, hyperbaric chamber four part, main busbar and a HV Terminal are installed in bus-bar room, hyperbaric chamber is arranged on the upper back of cabinet, high pressure detecting element is provided with in hyperbaric chamber, the components and parts of high pressure detecting element and necessity are arranged in cabinet, reduce the volume of handcart, alleviate the weight of handcart, ensure that reliability of operation, handcart for subsequent use is without installation high-voltage detecting element simultaneously, reduces handcart cost; In addition, handcart room is formed below breaker chamber, the both sides inwall of breaker chamber is provided with guide rail, handcart both sides are provided with the guide support face coordinated with guide rail, handcart can advance easily and exit breaker chamber, there is the advantages such as operation is easy and convenient, transmission efficiency is high, accurate positioning, decrease the workload of field maintenance person, push and exit operating grip and be installed on circuit breaker cart, convenient and safe pushing exits handcart operation, and its smart structural design is reasonable, and space utilization is compact, convenient operating maintenance, meets instructions for use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model portable type direct-current traction power supply switchgear.
Embodiment
Below in conjunction with the drawings and specific embodiments, portable type direct-current traction power supply switchgear of the present utility model is described in further detail.
As shown in the figure, portable type direct-current traction power supply switchgear of the present utility model, portable type direct-current traction power supply switchgear, comprises cabinet 1 and handcart 7, and cabinet 1 is made up of breaker chamber 2, low-pressure chamber 3, bus-bar room 4, cable vault 5, hyperbaric chamber 6 four part; Breaker chamber 2 is arranged on the front lower portion of cabinet, and low-pressure chamber 3 is arranged on the front upper part of cabinet, low pressure indoor location low voltage component and control protective unit; Breaker chamber 2 and low-pressure chamber 3 are respectively arranged with independently room door; Bus-bar room 4 and cable vault 5 are arranged on the rear portion of cabinet, are provided with main busbar and a HV Terminal in bus-bar room 4, can also be configured in bus indoor location isolating switch etc. according to the demand of user; Hyperbaric chamber 6 is arranged on the upper back of cabinet, current-voltage measurement device and LTU line test unit are installed in hyperbaric chamber, high pressure detecting element is also provided with in hyperbaric chamber 6, a handcart room 8 is formed below breaker chamber 2, the both sides inwall of breaker chamber 2 is provided with guide rail 9, handcart 7 both sides are provided with the guide support face coordinated with guide rail, and the front end of guide rail 9 is provided with and handcart can be made to be pushed into guiding surface 10 in handcart room smoothly, makes handcart 7 to push thus and releases handcart room 8.
Furtherly, guide rail 9 is fixed on the sill of breaker chamber 2 both sides, handcart converts in service position and test position easily by guide rail, the front column of breaker chamber 2 is provided with handcart and safeguards locking module 11, be made up of the fixture be contained on handcart and the rotating fixture be contained on the left of cabinet, its effect is misused pull-out cabinet when preventing handcart at non-installation and maintenance dolly, causes accident.
