Problems solved by technology

Arranging fences in the protection room is not only time-consuming and laborious, but also brings inconvenience to the passage of professional protection personnel; when the red curtain isolates the operating equipment, it is easy to fall off and cannot be fixed, and hinders the monitoring of the operating equipment; these measures are very inconvenient to implement
At the same time, the secondary measures for the on-site operations of the protection personnel are not ideal. The thread ends temporarily removed by them are only wrapped with adhesive tape, which cannot be effectively protected, and there is a possibility of accidental contact; Isolation, there is a pos

Embodiment 1

[0032] This embodiment is a protective cap on the end of the secondary cable core in the isolation relay protection cabinet of the power industry, such as Figure 1c , 1d Shown. The end of the secondary cable core generally has a fork-shaped connecting piece. The connecting piece is a copper piece. After disassembly, the connecting piece may contact other devices, causing false signal. The secondary cable core protective cap is a hollow cap body 11, one end of the cap body 11 is open and the other end is closed, and the closed end is a handle 12. The cap body 11 is in the shape of a flat barrel, and the shape of the handle 12 is flat. The handle is a solid handle made by compression of the cap body, which is convenient for pinching. The whole of the protective cap is made of elastic non-transparent insulating material, and the inner hole and length of the cap body are adapted to the end of the secondary cable core to be protected and sleeved on the end of the secondary cable co...

Embodiment 2

[0034] This embodiment protects the pressure plate in the isolation relay protection cabinet of the electric power industry. The pressure plate is also called a pressure plate or a terminal. A conductive connecting piece is connected between the two pressure plates. After the connecting piece is removed, in order to prevent Incorrect connection, the two pressure plates need to be protected. The shape of this embodiment is the same as Figure 1c , 1d As shown, the difference from Embodiment 1 is that the cap body 11 and the handle 12 of the protective cap are relatively large, which can protect the two pressing plates at the same time.

Embodiment 3

[0036] In this embodiment, the pressing plate of embodiment 2 is individually protected. This example Figure 1a , 1b As shown, the difference from Embodiment 1 is that the cap body 1 is barrel-shaped, corresponding to the shape and size of a single pressing plate, and is sleeved on a single pressing plate.

Abstract

The invention discloses a safe guarding device for a power relaying protection field work and a use method thereof. The safe guarding device comprises a guarding device and an isolating device, wherein the guarding device is used for maintaining the work, and the isolating device is used for operating the work. The guarding device for maintaining the work comprises a secondary cable core guardingcap, a guarding cap, a terminal block guarding fence and a protection work voice prompter, which are used for protecting a cable core, a pressing plate and a terminal block. The isolating device for operating the work comprises a protecting screen safety isolating guardrail, a protecting device isolating cover, a protecting pressing plate isolating cover, a terminal block isolating cover, a secondary security isolating cover, a CT externally attached terminal isolating cover, a security temporary storage box, a working signboard and an operation handle isolating cover, which are used for isolating and protecting equipment. Each guarding device is adhered with a marking note corresponding to the work state. The safe guarding device has the advantages of fixation, reliability, obvious mark,simple operation, norm and cleanness, and no influence to operation of the equipment by a magnetic field of a magnet, and is suitable for isolating and protecting various kinds of relay protection equipment and devices.

Description

Technical field [0001] The present invention relates to a protective device and a method of use in the power industry, in particular to a safety protective device and method of use for professional field operations of relay protection in the power industry. Background technique [0002] The equipment in the electric power industry is mainly divided into high-voltage operation equipment and relay equipment that controls high-voltage operation. Relay equipment is also called secondary equipment. The normal operation of relay equipment is the guarantee for the normal operation of power. Maintaining the normal operation of the relay equipment needs to be completed by operating personnel and professional protection personnel. The operating personnel are responsible for the normal operation of the operating equipment, and the protection personnel are professional maintenance personnel who are responsible for the maintenance of the equipment out of service. Relay protection in the power...
