Abstract
Provided by the utility model is a high-voltage isolation switch for an electric locomotive. Lower portions of two insulators of the high-voltage isolation switch are connected to and fixed on a base plate by flange bolts; a wiring board is fixed at the upper portion of one insulator and a disconnecting link cooperated with a tool holder is fixed at the upper portion of the other insulator; a static contact piece is arranged at the upper portion of the wiring board; and a mounting rack is arranged at the lower portion of the base plate. According to the utility model, the beneficial effects of the high-voltage isolation switch are as follows: the running condition of high-voltage equipment in the 25-kV circuit is configured optimally; and when a fault occurs at the top equipment, the fault can be isolated partially to maintain the running of the locomotive, thereby substantially reducing the machine-breaking accident due to the fault of the top equipment and thus ensuring the secure running of the locomotive. Moreover, the provided high-voltage isolation switch has advantages of reasonable structure, convenient operation, good application effect, stable and reliable working state and low contact resistance and the like; and the requirement of normal and secure running of the electric locomotive can be met.
Description
Technical field
The utility model belongs to the high voltage isolator of roof protective device, particularly a kind of use for electric locomotive high voltage isolator.Its Main Function is the operating condition of distributing 25kV circuit inner high voltage equipment rationally, and when roof apparatus breaks down, faulty component can be isolated, and keeps locomotive operation.
Background technology
High voltage isolator is the requisite vitals of electric locomotive, and the contact of existing electric locomotive high voltage separation switch disconnecting link and static contact is little, and contact resistance is large, causes the isolating switch operation unreliable, has affected performance and the life-span of switch.
Summary of the invention
For deficiency of the prior art, the purpose of this utility model is to provide a kind of use for electric locomotive high voltage isolator, and is rational in infrastructure, easy to operate, and result of use is good, and stable working state is reliable, and contact resistance is little, satisfies that electric locomotive is normal, safe operation.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of use for electric locomotive high voltage isolator, and wherein: this high voltage isolator includes two insulators, terminal block, cutter holder, disconnecting link, base plate, static contact, installing rack; The bottom of described two insulators is fastened on base plate by flange plate bolt, one insulator top is fixed with terminal block, another insulator top is fixed with the disconnecting link that matches with cutter holder, and described terminal block top is provided with static contact, and the bottom of base plate is provided with installing rack.
Effect of the present utility model is that this high voltage isolator belongs to the roof protective device.Its Main Function is the operating condition of distributing 25kV circuit inner high voltage equipment rationally, and when roof apparatus breaks down, faulty component can be isolated, and keeps locomotive operation.Therefore, its existence can greatly reduce the accident of locomotive defect that causes because of the roof apparatus fault, guarantees the safe operation of locomotive.
The advantages such as this high voltage isolator has rational in infrastructure, and is easy to operate, and result of use is good, and stable working state is reliable, and contact resistance is little satisfy that electric locomotive is normal, the requirement of safe operation.

Embodiment
By reference to the accompanying drawings the structure of use for electric locomotive high voltage isolator of the present utility model illustrated.
As shown in Figure 1 and Figure 2, the utility model use for electric locomotive high voltage isolator, this high voltage isolator include two insulators 1, terminal block 2, cutter holder 3, disconnecting link 4, base plate 5, static contact 6, installing rack 8; The bottom of described two insulators 1 is fastened on base plate 5 by flange plate bolt, one insulator 1 top is fixed with terminal block 2, another insulator 1 top is fixed with the disconnecting link 4 that matches with cutter holder 3, and described terminal block 2 tops are provided with static contact 6, and the bottom of base plate 5 is provided with installing rack 8.
Isolating switch disconnecting link 4 is large with the contact of static contact 6, and contact resistance is little.
The utility model use for electric locomotive high voltage isolator generally is arranged on locomotive roof.Take base plate 5 as the boundary, be divided into upper and lower two parts.Top is high-pressure section, mainly comprise insulator 1, disconnecting link 4, cutter holder 3 etc., the bottom of described two insulators 1 is fastened on base plate 5 by flange plate bolt, and insulator 1 top is fixed with terminal block 2, and another insulator 1 top is fixed with the disconnecting link 4 that matches with cutter holder 3.The bottom is the transmission operation part, mainly comprises mechanical interlocking, electrical interlock and operating grip etc.The utility model effect is rational in infrastructure, and is easy to operate, and stable working state is reliable, and contact resistance is little, satisfies that electric locomotive is normal, safe operation.The utility model highly versatile is applicable to various electric locomotive.
The utility model use for electric locomotive high voltage isolator operation logic is: when high voltage isolator is in "on" position, if separating brake, must first with key, mechanical interlocking be opened, then by the separating brake direction rotating operation handle of label indication after hand wheel rotating puts in place, then mechanical interlocking is locked.At this moment, isolating switch is in gate-dividing state.When high voltage isolator was in gate-dividing state, if require to close a floodgate, its process and separating brake process were much the same, also must first with key, mechanical interlocking be opened, then press the combined floodgate direction turning handle of label indication, after handle rotate in place, then mechanical interlocking is locked.At this moment, isolating switch is in "on" position.
