Abstract
The invention discloses an electricity testing auxiliary handcart with a centrally-mounted enclosed type switch cabinet, which consists of a body, a connecting plate and a propeller, wherein the body and the connecting plate are connected together through the propeller arranged inside the handcart; one end of the propeller is provided with a rocker handle; two sides of the front end of the body are provided with propelling plates; and two sides of the body are provided with roller wheels. The connecting plate is provided with to bar holes with opposite positions, a handle is arranged in the bar holes, a spring is arranged between one end of the handle and a clapboard in the connecting plate, the other end of the handle is connected with a locking plate, and the other end of the locking plate passes through a lateral plate of the connecting plate and is arranged outside the connecting plate. The electricity testing auxiliary handcart uses the action of pushing and closing a baffle plate by the body to push away and close an electrified body closed baffle plate so as to avoid direct grounding operations on site without effective electricity testing and realize that people are far away from an electrified body; besides, the electricity testing auxiliary handcart ensures the safe working distance, and can avoid electrified installation of a grounding wire device, prevent a human body from electric shocks, and ensure the safety of electric power work.
Description
Technical field
The present invention relates to State Grid Corporation of China and the 10KV of transformer station of certain customers middle switchgear and identify the whether charged a kind of device of equipment.
Background technology
Since two nets were transformed, newly-built, transformation electrical engineering project adopted the middle sealing switch equipment in a large number.The main feature of this equipment is that specification of equipment is little, and highly integrated, floor space is little, has obtained the favor of domestic power-generating enterprise.But there is following shortcoming in this equipment in manufacturing and designing: according to the relevant requirements of " electric power safety working regulation ", equipment has a power failure when overhauling (or line maintenance), needs the installing earth connection; Operating personnel are when being inspecting state with equipment by the operating state transfer; at first need electrical verification; its objective is based on protection operating personnel's person and handling safety; the electrical verification program is necessary; because this equipment is for closed; its shell protection grade is generally more than the IP3X; the conventional electroscopic device that electric power enterprise is equipped with can't carry out normal electrical verification operation at all; the charged display unit that only relies on equipment itself to be equipped with; charged display unit can only be obtained parameter indirectly; the work of part display unit is unreliable also to be to cause operating personnel's erroneous judgement disconnected, causes the electric power safety production accident.Personnel in the unconventional course of work of otherwise address and charged position can not guarantee distance problem fully.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, provide a handling safety reliable, convenient, the auxiliary handcart of mid-enclosed switchgear electrical verification that electrical verification is straightforward.
The present invention is achieved by the following technical solutions:
Handcart is assisted in a kind of mid-enclosed switchgear electrical verification, and it is made of car body, connecting plate and propeller, and the propeller that is provided with by inside between described car body and the connecting plate links together, and an angle of rake end is provided with crank; Both sides at the car body front end are provided with pushing plate, and the car body both sides also are provided with roller.
Connecting plate is provided with two relative bar holes of position, and bar hole is built-in with handle, is provided with spring between the dividing plate in an end of handle and the connecting plate, and the other end of handle is connected with latch plate, and the side plate that the other end of latch plate passes connecting plate places outside the connecting plate.
Advantage of the present invention is: application class of the present invention is like the configuration design of wheelbarrow switch underframe, to satisfy electrical production work on the spot demand; Utilize the slippage effect of baffle plate of car body simultaneously, reach and push open and closed electrified body closed guard, thereby avoid on-the-spot electrical verification not yet in effect and directly carry out the ground connection operation, and particular job environment personnel directly carry out the dangerous operation of push-and-pull electrified body closed guard, the realization personnel are away from electrified body, guarantee the trouble free service distance, handling safety, convenience.This invents simple in structure feasible, can avoid charged installing earth connection equipment, prevents that the person from getting an electric shock, and ensures work about electric power safety.
Description of drawings
Figure is a structural representation of the present invention.
Embodiment
Embodiment: handcart is assisted in mid-enclosed switchgear electrical verification as shown in the figure, and it is made of car body 1, connecting plate 5 and propeller 4, and the propeller 4 that is provided with by inside between described car body 1 and the connecting plate 5 links together, and an end of propeller 4 is provided with crank 6; Both sides at car body 1 front end are provided with pushing plate 2, and car body 1 both sides also are provided with roller 3.Described connecting plate 5 is provided with two relative bar holes 11 of position, bar hole 11 is built-in with handle 8, be provided with spring 7 between the dividing plate 10 in one end of handle 8 and the connecting plate 5, the other end of handle 8 is connected with latch plate 9, and the side plate that the other end of latch plate 9 passes connecting plate 5 places outside the connecting plate 5.
During use car body 1 is placed on the circuit breaker floor truck or directly this car body 1 is put in the switch cubicle, car body 1 is pushed on the switch cubicle inner breaker track.Should note this device can not being pushed into by force the service position of former circuit breaker this moment, can only be with it as for test position, promptly the latch plate 9 of handle 8 both sides is inserted in the obturator hernia.Rotate crank 6 then this car body 1 is slowly advanced, in the progradation, the metal baffle of sealing electrified body will be upspring automatically, expose charged position.In the progradation as observe pushing plate 2 closed guard is opened fully, should stop into car operation.According to the requirement of power industry rules, wear corresponding protective device, require to carry out electrical verification according to program.When identify needed outlet side or bus bar side not charged after, car body 1 is withdrawed from, carry out the ground connection operation.
